Subtracting Mixed Numbers<br />
In order to subtract a mixed number from a whole number, the whole number<br />
needs to be renamed as a mixed number. Make the denominator of its fraction<br />
the same as the denominator of the other fraction.<br />
For example: 5 – 2 ⅘<br />
1. Change the whole number 5 to a mixed number.<br />
2. 5 can be changed to 4 and .<br />
3. Subtract the whole numbers and then subtract the fractions.<br />
4. The answer is<br />
Unlike Fractions<br />
Unlike fractions do not have the same denominator. To compare, add, or<br />
subtract these unlike fractions, they have to be renamed with the least common<br />
denominator. To find the least common denominator of two fractions, list the<br />
multiples of each fraction.<br />
For example: Find the least common denominator for 1/4 and 5/6<br />
1. Multiples of 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36…<br />
2. Multiples of 6 = 6, 12, 18, 24, 30, 36…<br />
3. Common multiples = 12, 24, 36.<br />
4. The least common multiple is 12 therefore the common denominator is 12.<br />
5. Rename the fractions changing both denominators to 12.<br />
