218 CHAPTER 4. INTRODUCTION TO FRACTIONS AND MULTIPLICATION AND DIVISION OF FRACTIONS Exercise 4.2.1 (Solution on p. 278.) 4 7 Exercise 4.2.2 (Solution on p. 278.) 5 8 Exercise 4.2.3 (Solution on p. 278.) 10 15 Exercise 4.2.4 (Solution on p. 278.) 1 9 Exercise 4.2.5 (Solution on p. 278.) 0 2 4.2.5 Reading and Writing Fractions In order to properly translate fractions from word form to number form, or from number form to word form, it is necessary to understand the use of the hyphen. Use of the Hyphen One of the main uses of the hyphen is to tell the reader that two words not ordinarily joined are to be taken in combination as a unit. Hyphens are always used for numbers between and including 21 and 99 (except those ending in zero). 4.2.5.1 Sample Set B Write each fraction using whole numbers. Example 4.5 Fifty three-hundredths. The hyphen joins the words three and hundredths and tells us to consider them as a single unit. Therefore, fty three-hundredths translates as 50 300 Example 4.6 Fifty-three hundredths. The hyphen joins the numbers fty and three and tells us to consider them as a single unit. Therefore, fty-three hundredths translates as 53 100 Example 4.7 Four hundred seven-thousandths. The hyphen joins the words seven and thousandths and tells us to consider them as a single unit. Therefore, 400 four hundred seven-thousandths translates as 7,000 Example 4.8 Four hundred seven thousandths. The absence of hyphens indicates that the words seven and thousandths are to be considered individually. four hundred seven thousandths translates as 407 1000 Write each fraction using words. Example 4.9 translates as twenty-one eighty-fths. 21 85 Example 4.10 200 3,000 translates as two hundred three-thousandths. A hyphen is needed between the words three and thousandths to tell the reader that these words are to be considered as a single unit. Available for free at Connexions
219 Example 4.11 translates as two hundred three thousandths. 203 1,000 4.2.5.2 Practice Set B Write the following fractions using whole numbers. Exercise 4.2.6 (Solution on p. 278.) one tenth Exercise 4.2.7 (Solution on p. 278.) eleven fourteenths Exercise 4.2.8 (Solution on p. 278.) sixteen thirty-fths Exercise 4.2.9 (Solution on p. 278.) eight hundred seven-thousandths Write the following using words. Exercise 4.2.10 (Solution on p. 278.) 3 8 Exercise 4.2.11 (Solution on p. 278.) 1 10 Exercise 4.2.12 (Solution on p. 278.) 3 250 Exercise 4.2.13 (Solution on p. 278.) 114 3,190 Name the fraction that describes each shaded portion. Exercise 4.2.14 (Solution on p. 278.) Exercise 4.2.15 (Solution on p. 278.) In the following 2 problems, state the numerator and denominator, and write each fraction in words. Exercise 4.2.16 (Solution on p. 278.) The number 5 9 is used in converting from Fahrenheit to Celsius. Exercise 4.2.17 (Solution on p. 278.) A dime is 1 10 of a dollar.
