INTRODUCTION
Hi! I’m EdWIN!
Hi, my name is EdWIN. I will be your guide
through Applied Mathematics. We will go
through this course together. Look for me to
pop up throughout your lessons to give you
helpful tips.
Now, don’t get nervous. I know how many
of you feel about math, especially when the word
fraction is mentioned. We will cover one topic
at a time. I will be here to give you examples to
help you along.
If the content of the lesson is something that
you understand, you should be able to work
through it at a faster pace. If the material is
difficult, read the text several times. Then, try
to work the exercises one at a time. After you
try one problem, look at the solution. You can
learn by reviewing each step that is provided in
the solution. Think about the process being
shown. Now, think positive. Negative attitudes
are not allowed!
Applied Mathematics is a course designed to
help you solve math problems. It is important
that you have basic math skills. It is also
important that you can apply them to problems
that arise on your job. The main focus of this
level of Applied Mathematics is to learn the basics.
We will start at the very beginning.

LESSON 2
RECOGNIZING
BASIC MATH SYMBOLS
You’re about to start Lesson 2. You must have
done well on the Pretest. This lesson is going to
teach some basic math symbols. Sometimes, we
call symbols signs. You may know some of them.
If that is the case, that’s great.
There are a lot of signs in math. People who
do a lot of math like shortcuts. Symbols are easier
and faster to write than writing words. Symbols
are used for math processes. Here are the symbols
we will look at in this lesson.
MATH SYMBOLS
+ add - subtract × multiply
÷ divide = equal % percent
$ dollar ¢ cent @at
# number/pound ° degree
SALE
25% OFF
We will go over each symbol and talk about
what it means. You will need to practice
remembering the ones you do not know. We
are going to start with symbols that mean a math
process.
What symbol do you
see
Applied Mathematics • 15
LESSON 2
Addition
Let’s begin by looking at the + (plus) sign.
This symbol means to add. If you see 4 + 5, you
should add four and five. Four books plus five
books adds to nine books.
is
I will not try to teach you to add in this
course. This lesson is about symbols. In the next
level, I will show you how to add using a
calculator. For now, I want you to know the
symbol used to show addition. When we read
4+5, we say 4 plus 5.
16 • Applied Mathematics
LESSON 2
Subtraction
Next, let’s talk about the minus sign. It looks
like this: - . This sign means to subtract. It is the
opposite of the plus or addition sign. If you have
9 - 5, you take five away from nine.
For example:
Do you see that if you have 9 books and 5 are
taken away, you have 4 left
Some people say the minus sign means take
away or less.
9 - 5
This is read as 9 minus 5. You might think:
9 take away 5
or
9 less 5
Applied Mathematics • 17
LESSON 2
Some minds like to think:
5 less than 9
Five numbers less than nine is the number four.
This process is called subtraction.
Equal
The answers to math problems are often
found after the symbol =. It means equals or is
equal to. Earlier, we had:
4 + 5
four plus five
We said when you add 4 and 5, the answer is 9.
We write this phrase like this:
4 + 5 = 9
four plus five equals nine
Some people might say the result of working a
math process follows the equals sign.
18 • Applied Mathematics
LESSON 2
Multiplication
Multiplication is really a fast way to add. We
use the symbol × to mean multiply. When you
see 3 × 4, it means the number 3 is to be
multiplied by the number 4. We often say,
3 times 4. That is because in multiplication, you
are counting the same number multiple times.
In this example, 3 × 4, you are counting a group
of 4 … 3 times.
groups of 4 - 3 times
Do you see why I said multiplying is really
counting fast Instead of making a drawing to
count, we learn the fact that 3 groups of 4 equals
12.
Applied Mathematics • 19
LESSON 2
There are many jobs where you may need to
multiply, such as carpentry, landscaping, and
decorating. Being able to multiply helps you do
some jobs faster. There are basic multiplication
facts that are taught in school. I hope you
remember them. If you have not needed to
multiply often, you may have forgotten them.
Do not worry. We will learn to multiply using a
calculator in the next level.
However, you may not always have a
calculator handy. If you know some of the facts,
but have forgotten others, you may use the table
to review.
The numbers across the top and the left side
of the chart are your guides. The problem 10 × 7
is read ten times seven. Find the 10 on the left
side of the chart and touch the 10 with a finger
on your left hand. Find the 7 at the top of the
chart and touch the 7 with a finger on your right
hand. Slide your fingers over the chart as shown
until they meet. You should see the number 70.
Ten times seven equals seventy.
20 • Applied Mathematics
LESSON 2
MULTIPLICATION TABLE
1 2 3 4 5 6 7 8 9 10
2 4 6 8 10 12 14 16 18 20
3 6 9 12 15 18 21 24 27 30
4 8 12 16 20 24 28 32 36 40

8 16 24 32 40 48 56 64 72 80
9 18 27 36 45 54 63 72 81 90
10 20 30 40 50 60 70 80 90 100
Let’s try another problem: 5 × 8. Find the 5
on the left side of the chart. Find the 8 on the
top. You should find that five times eight is forty.
If you do not know these facts, you might
want to try learning them by making a set of
cards. Write the problem on one side of a card
or paper. Write the problem and answer on the
other side. Start with 5 to 10 cards. If you start
with too many, you might get frustrated.
Applied Mathematics • 21
LESSON 2
From time to time, look at the sides of the
cards without the answer. See if you know the
answer. If you do not remember it, turn the card
over. Studying multiplication facts will help you
learn them. Practice a few at a time until you
begin to remember them. Then, try adding new
facts to your set.
This can be a hard process. You do not have
to know how to multiply to complete this course.
Knowing at least some facts will make it easier
at times.
Practice if you
want to learn multiplication facts.
22 • Applied Mathematics
LESSON 2
Division
The next symbol we will look at is the division
sign. This means the opposite of multiplication.
We said that 5 × 8 = 40. If we go backward,
40 ÷ 8 = 5. This is read as forty divided by eight
equals five. Forty can be divided into eight equal
parts. Look at the following example of division.
An office with 4 workers won the local radio station’s
morning breakfast. The station sent 12 doughnuts.
How many doughnuts can each worker have
12 doughnuts ÷ among 4 workers
Each worker gets 3 doughnuts when the 12 are
divided.
12 ÷ 4 = 3
These symbols, +, -, ×, and ÷, have
introduced the four basic math operations. Now,
let’s look at some other math symbols.
Applied Mathematics • 23
LESSON 2
Money
You probably know the dollar sign when you
see it. The dollar symbol looks like this: $. We
put it in front of dollar amounts. When we write
four dollars in symbols, we write $4.00. We
always write the $ symbol in front of the amount.
We sometimes use the cent symbol, which looks
like this: ¢. This sign goes behind the amount.
Four cents can be written as 4¢. Remember that
4 cents is part of a dollar, so it can also be written
as $.04. We will talk about how to write amounts
of money in another lesson.
You may not know the next few symbols.
They are not used as much as the others. Hang
in there, though. They’re not too difficult.
I like these symbols.
24 • Applied Mathematics
LESSON 2
Percent
Another symbol that is used to give important
information is the percent sign, %. Percents are
commonly used in the business world. They are
used to measure things like taxes and interest.
Percents are a way of describing parts of a whole.
With percents, one whole is divided into 100
parts. When referring to a percent, it means out
of 100. For instance, look at Figures A and B.
Figure A Figure B
In Figure A, all of the squares (the 100 parts
of this whole) are shaded. It means 100%. We
put the sign % after the number. When you hear
or say, 100% of something, this means all of it.
In Figure B, 50 of the squares are shaded.
This shows 50%. Notice 50 out of 100 is onehalf.
Applied Mathematics • 25
LESSON 2
Most of the time when percents are used,
visuals like Figures A and B will not be shown.
You should know what it means when you hear
different percents. For example, you might hear
that 25% of your wages are withheld for taxes.
25%
25%
If you are paid $100, then $25 will be
withheld. Your take-home pay will be $75.
Twenty-five percent of your wages goes to pay
taxes. Again, remember percent is based on 100.
26 • Applied Mathematics
LESSON 2
Other Symbols
The @ symbol is sometimes used in math
problems. To say that we have 4 items at 10¢
each, we write: 4 @ 10¢. In math, if you use the
word at, you may use this symbol. This symbol
is also used in Web addresses.
A symbol for the word number is #. It’s really
a shorthand symbol. I can write the number four,
or I can write #4. It’s a short way to write the
word number. This same symbol is sometimes
used to mean pounds. We write that the
computer weighs 15#. If the symbol is before a
number, it means number. If it follows a
number, it means pounds.
#10 number 10
10# 10 pounds
Applied Mathematics • 27
LESSON 2
The last symbol we will talk about is called
the degree symbol. It looks like a small circle.
You will see it when you read temperatures. If it
is sixty degrees outside, you could write 60°. You
may also see it when referring to angles. If you
do carpentry work, you have worked with ninety
degree angles. This is written as 90°. It is read as
ninety degrees. Though we will not study angles,
you should know the sign for degree.
Symbols have meanings. Most of them are
shorthand for words. Let’s see if you can
remember what the symbols mean by doing the
following exercise. The answers will follow. Good
luck!
I hope you can remember what all
of these math symbols mean.

TELLING TIME
To begin this lesson, let’s review counting by
5s. You need this skill when reading a clock face.
Since there are 60 minutes in an hour, we will

LESSON 3
Knowing how to count by fives will help you
tell time. If you already know how to tell time,
turn to page 42. Here you will find the exercise
for Lesson 3. Make sure you can do all of these
problems. If so, move on to Lesson 4. If you do
not know how to tell time, follow me and I will
show you how.
This is a clock face.
Figure 1
Look around your home or workplace and
find a clock that has numbers on it like the one
in Figure 1. You may find more than one kind
of clock. The kind with lighted numbers as in
Figure 2 is called a digital clock.
Applied Mathematics • 33
LESSON 3
7:32
Figure 2
Digital clocks show time in the standard written
format:
hour : minutes past the hour
The time 7:32 means it is 32 minutes after 7
o’clock. What does 4:05 mean It is five minutes
after 4 o’clock. It is easier to read a digital clock
than a clock face.
Before we talk more about time, let’s review
some basic units that measure time.
Day
Hour
Minute
Second
period of light between one
night and the next; or 24
hours
one 24th part of a day; or
60 minutes
one 60th part of an hour; or
60 seconds
one 60th part of a minute
34 • Applied Mathematics
LESSON 3
If you’ve found a clock, take a look at it. It
probably has a knob so that you can move the
parts on the front. Turn this knob a few times.
The parts that move on the front are called
hands. In Figure 3, the longer hand is on the 12.
The shorter hand is on the 5.
5:00
Figure 3
The long hand is called the minute hand. The
short hand is the hour hand … the hour that it
is. In Figure 3, it is five o’clock, which is written
as 5:00.
On the hour (that is at one o’clock, 2 o’clock,
3 o’clock, and so on) the long hand always points
toward the 12. The short hand points to the
hour. Look at the following clocks to see what I
mean.
12:00 2:00 4:00 10:00
Figure 4
Applied Mathematics • 35
LESSON 3
Some clocks have a little hand that is
constantly going around the clock face. That
hand keeps track of seconds. It is called the second
hand. It will travel around the clock once in one
minute. Each time the second hand moves all
the way around the clock face, the minute hand
(long hand) will move once to show that one
minute has passed.
In the same way, the minute hand (long hand)
will move around the clock face once showing
that one hour has passed. When the minute hand
moves completely around the clock face, the
hour hand (short hand) will move to the next
hour.
As you have seen, the numbers 1 through 12
on your clock show the hour. The short hand
points to the hour. These 12 numbers are also
used to show minutes using the long hand. The
numbers are read in 5-minute increments.
1 means 5 minutes
2 means 10 minutes
3 means 15 minutes
4 means 20 minutes
5 means 25 minutes
6 means 30 minutes
7 means 35 minutes
8 means 40 minutes
9 means 45 minutes
10 means 50 minutes
11 means 55 minutes
36 • Applied Mathematics
LESSON 3
For example, look at Figure 5. When the short
hand is on the 2 and the long hand on the 3, we
say it is 15 minutes after 2. The short hand (hour
hand) tells you the hour is two o’clock. The long
hand (minute hand) is on the 3, which means
15 minutes. This clock shows 2:15. It is 15
minutes after two o’clock.

Figure 6
Some clocks will show the minutes like those
in Figure 6. If your clock does, start counting at
12. Move in a clockwise direction. In Figure 6,
you count to where the long hand points to the
3. The long hand shows that 15 minutes have
passed since 2 o’clock. Here are 2 more examples:
20 minutes after 3 o’clock 25 minutes after 11 o’clock (11:25)
(We write this as 3:20)
Figure 7 Figure 8
38 • Applied Mathematics
LESSON 3
When the long hand in on the 6, we can say
several things that mean the same time. Look at
Figure 9. It is 30 minutes after 2 o’clock. We
usually say it is two-thirty. We write this as 2:30.
2:30
Figure 9
When the long hand passes 6 and is on 7, it
is two thirty-five (2:35). There are 60 minutes
in an hour. If it is thirty-five minutes past one
hour, then it is 25 more minutes until the next
hour.
60 - 35 = 25
Look at Figure 10. Two thirty-five is often
called twenty-five minutes before three o’clock.
Sometimes we say 25 till 3. Do you see that they
are the same times
2:35 or twenty-five till three
Figure 10
Applied Mathematics • 39
LESSON 3
Here are some examples of time:
3:00 – three o’clock 2:05 – five after two 8:45 – fifteen till nine
3:22 – twenty-two after three 10:41 – nineteen till eleven 12:00 – noon or midnight
Since there are 24 hours in a day, the hour
hand must move around the clock face twice in
one day. The morning hours are shown by a.m.
(I get up at 7:00 a.m.) The afternoon and
evening hours are shown using p.m. The 12:00
after the morning hours is called noon. The
12:00 after the evening hours is called midnight.
40 • Applied Mathematics
LESSON 3
Remember, a digital clock simply tells the
correct time.
I2:45
It is forty-five minutes after twelve or twelve
forty-five. You could say it is (60 - 45 = 15) 15
minutes until 1 o’clock.
Practice telling time by looking at a clock face
and then a digital clock. They should tell the
same time.
Now, let’s practice a little. I’m going to show
you some clocks and ask you to match the correct
time. The answers will be provided afterward.
Try your best before you look. Good luck!

LESSON 4
READING SIMPLE METERS
In Lesson 3, you practiced telling time. Did
you know that you were reading a simple meter
Meters are devices used to measure things. You
could say a clock measures time. You may not
realize it, but you probably read other meters all
the time. We have to read rulers, timers, scales,
speedometers, and a number of things that
measure using numbers.
A common meter is the scale. Scales are
instruments or machines used for weighing. The
instruments must have a part that has marks to
show expected measures and a pointer. For
instance, the scales in a doctor’s office might look
something like this:
2 4 6 8 10 12 14 16 18 20
You never know when
you might need to
read a meter.

Home Scales
Figure 12
Both types of scales have marks to show
different possible weights and a pointer. The
pointer shows the measurement of the object
being weighed. Most meters work the same way.
Thermometers are another type of meter.
They measure temperature. Some thermometers
have a pointer. Others may have a liquid that
rises to the point showing the temperature. (see
examples shown in figure 13 on the following
page)

How are you doing Don’t be afraid of math.
Try to think of it as a game. The more you play
or practice, the better you will be at playing.
Lesson 5 is about reading whole numbers.
Whole numbers are the numbers beginning with
zero:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and so on
Digits are used to write whole numbers.
There are ten digits. They are:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
The position of a digit in a number shows its
place value. Let’s start by looking at a place value
or position chart.
Place Value Chart
ones (units)
Applied Mathematics • 53
LESSON 5
When we write a number, each digit has a
place. Look at the number 52. We line up the
ones place with the 2, and the 5 will be in the
tens place. This means there are 2 units of one
and 5 tens.
5 GROUPS OF 10 2 ONES
tens
5 2
ones (units)
Where a digit is located in a place value chart
tells the place value of that digit. Look at the
digit 9 in the following numbers:
Hang in there. Place
value is very important.
935
91
9
The value of the digit is nine. The place value
varies. In 935, the 9 means 9 hundreds. In 91,
the 9 means 9 tens. In the number 9, the 9 means
9 ones.

The 4 is in the hundreds place, and we say or
write four hundred. The tens place is always
written with numbers counting by tens: ten,
twenty, thirty, forty, fifty, sixty, seventy, eighty,
or ninety. In this case, we have six in the tens
place, so we say or write sixty. The ones place is
written just like we talk: one, two, three, four,
five, six, seven, eight, or nine. In this number,
we have eight (ones).
62 • Applied Mathematics
LESSON 6
Let’s practice writing another number in
words. Think about the number 11,035,018.
First, we place the digits on the place value chart.
_ 1 _ 1 _ , _ 0 _ 3 _ 5 , 0 _ 1 _ 8_
ones
millions

The first two digits fall in the set of millions,
so we write eleven million. The comma tells us
to move to the next set, which is thousands. We
would write thirty-five thousand. There is
another comma, so we move to the set of ones
and write eighteen. The number 11,035,018
would be written in words as eleven million,
thirty-five thousand, eighteen.

LESSON 7
RECOGNIZING PLACE
VALUES IN MONEY
Lesson 7 also uses place value. As I said, the
place value chart keeps adding places to the left
as numbers get bigger.
Now, let’s think about that for a minute. As
we add places to the left, we can show numbers
getting larger. What if I add a place value to the
right of the ones place Will I show numbers
smaller than one The answer is yes. However, I
have to have a way to show where the ones place
is located. We use a dot called a decimal point. A
decimal point is placed after the number that is
in the ones place. The decimal point makes it
possible to show place values less than one.
I want to know all about money.
Applied Mathematics • 71
LESSON 7
5 ones can be written as:

There are often reasons to show these place
values. Money is an example where we need to
be able to show amounts less than one. We write
amounts of money using two places to the right
of the decimal point. Therefore, let’s talk about
these two place values.
hundred thousands

72 • Applied Mathematics
LESSON 7
I want to keep this lesson as simple as possible.
I do not plan to explain decimals. At this level,
you should know that decimals or numbers to
the right of a decimal point show amounts less
than one. The place value just to the right of the
decimal point shows tenths and the next place
shows hundredths. Be careful as you study tenths
and hundredths because their names are so close
to tens and hundreds. Remember they are on
the other side of the decimal point. The th on
the end of the words will help remind you that
tenths and hundredths are parts of one whole.
Money is often shown using tenths and
hundredths. One dollar and twenty-five cents
is written as $1.25. We read the decimal point
as the word and. We say one dollar and twentyfive
cents.

about money.

LESSON 8
COUNTING MONEY
Lesson 8 is about counting money. We’re
going to practice counting money and see
different ways to write it. You may already know
how to count money. If you do, you may move
on to the practice problems at the end of this
lesson. It is a good idea, even if you know how
to count money, to do these problems for review.
Usually, it’s not as easy to write units of money
as it is to count them.
Money comes in several forms. Let’s take a
look at some of them:
penny nickel dime quarter
$.01 $.05 $.10 $.25
one-dollar bill
five-dollar bill
$1.00 $5.00
ten-dollar bill
twenty-dollar bill
$10.00 $20.00
Applied Mathematics • 75
LESSON 8
Remember, the symbol $ means dollars. It
means money is being shown. There are 100
pennies in one dollar. We usually show the
number of pennies or cents using the hundredths
place value. Do you remember the hundredths
place from the last lesson
$.08 8 cents
$.02 2 cents
The amount, $.10, shows ten pennies or ten
cents. Notice the decimal point. Two places to
the right of it shows hundredths. This means
we have 10 out of 100 pennies (or one dollar).
We write 50 cents or 50 pennies as $.50.
Sometimes a zero is placed in the ones place:
$0.50
This means the same amount as $.50.
Remember …
$ dollars
¢ cents
76 • Applied Mathematics
LESSON 8
We can also write this amount as 50¢ using a
different symbol that shows money. The symbol
¢ means cents. Earlier I wrote $.05 under the
picture of the nickel. We read this as five cents
even though we write a dollar sign in front of it.
The placement of the 05 to the right of the
decimal shows that a nickel is part of a dollar. In
the same way, we can write $.25 for 25 cents.
Can you read these amounts
$.01 = 1 cent (1¢ or 1 penny)
$.05 = 5 cents (5¢ or 1 nickel)
$.10 = 10 cents (10¢ or 1 dime)
$.25 = 25 cents (25¢ or 1 quarter)
$1.00 = 1 dollar
$5.00 = 5 dollars
$10.00 = 10 dollars
Applied Mathematics • 77
LESSON 8
Pennies are counted by ones. If we have 4
pennies, we have 4 cents. Nickels are counted
by fives since a nickel means the same as 5
pennies. (5, 10, 15, 20, 25, 30, 35, 40, …)
If I have two nickels,
I count by fives — 5,10 — I have 10 cents.
If I have 4 dimes,
I count by tens — 10, 20, 30, 40 — I have 40
cents.
If I have 3 quarters, I count by 25s.
25, 50, 75 — I have 75¢
78 • Applied Mathematics
LESSON 8
If I have 4 quarters, I have $1.00. This means
that every time I have four quarters, I will have
$1.00.
Let’s practice counting money together. You
must know how much each coin is worth. If
you do not, review page 75.
When counting money, start with the coins
that have the greatest value.
quarter dime nickel penny
We have one quarter. It is worth 25¢. Then,
we have a dime. It is worth 10¢. Next, we have
a nickel worth 5¢. Last, we have 1¢.
Add:
• one quarter 25¢
• one dime 10¢
• one nickel 5¢
• one penny + 1¢
41¢
We have $.41 or 41 cents.
Applied Mathematics • 79
LESSON 8
Let’s look at another example.
25¢ + 25¢ + 1¢
We have $.51 or 51 cents.
one-dollar bill
five-dollar bill
ten-dollar bill
twenty-dollar bill
Paper money seems easier to count for some
people. It has the amount written on each bill.
As with coins, always start counting with the
bill of greatest value. This can make it easier to
count. If you have 20s, count by 20s. If you
have 10s, count by 10s. If you have 5s, count by
5s.
Let’s practice counting some bills.

LESSON 9
READING AND
WRITING FRACTIONS
You are almost finished with this workbook.
You only have one more lesson to do after this
one. You should be proud of your progress!
This lesson is about fractions. Fractions are
pieces of larger things. For instance, if you have
a piece of pie, you have a fraction of the pie.
Let’s take a look at some pictures that should
help you see this clearer.
This is one whole
sandwich. Soon there
will be one half left.
This is a whole circle. We can draw a line
through the center of the circle. When we do,
we have divided the circle in half (written 1 2 ).
Applied Mathematics • 91
LESSON 9
The circle is in two pieces. We have made
fractions, parts of a whole. To show a fraction,
we have shaded one of the two pieces. The
fraction is written:
1
2
This means one out of two parts.
The top number is the shaded part (called
the numerator). The bottom number is the total
number of pieces (the denominator).
Let’s look at another circle:
We have divided this circle into four pieces –
showing it as fourths.
92 • Applied Mathematics
LESSON 9
3
4
If we shade 3 of the 4 pieces, we have shaded
of the circle.
Now, think about the lesson on money. When
we talked about money, we said that every time
you had 4 quarters, you would have one dollar.
Four quarters makes one whole dollar. This
means that one quarter is 1 4
of a dollar.
(Sometimes when we write the fraction 1 4 , we
say one quarter of something.)

So,

LESSON 9
What part of a dollar is two quarters or fifty
cents
Fifty cents $.50 is half of a dollar.
25¢
50¢
25¢
Make sure that when you read fractions you
read the top number first. Then, read the bottom
number as half, third, fourth, fifth, and so on.
For example, 3 4
is read three-fourths.
The bottom number of a fraction shows how
many equal pieces make up the whole. The top
number shows how many pieces you are talking
about. The larger the number on the bottom,
the smaller the parts compared to the whole.
Think about that for a minute. Do you see the
parts getting smaller as the bottom number gets
bigger For example:
1
4
1
8
1
16
1
32
Which was larger, 1 4 or 1 Look at the
16
pictures. You can see 1 4 is larger than 1
16 . When
the top number is the same, the larger the
bottom number, the smaller the fraction.
94 • Applied Mathematics
LESSON 9
If the bottom number doesn’t change and the
top number gets larger, then you have more parts
of the whole. For example:
1
8
2
8
3
8
What is more, 1 8 or 3 The top number
8
means more parts. Three parts are more than
4
8
one part. Therefore, 3 8 is more than 1 8 .
What if the number on the top and the
bottom of the fraction are the same Then, you
have a whole, or 1.

A ruler is often marked off in inches. Each
inch is divided into halves, fourths, eighths, and
sixteenths of an inch.

We will not practice using fractions to
measure distance. You should see that fractions
are found in everyday activities, like using a ruler
to measure distance.
