**6.4 Adding and Subtracting Mixed Numbers**

2
**Adding Mixed Numbers Find the sum. 4 9 1 1 9 + 3 5 9 4**

Rewrite the fraction using LCD if denominators are different. 4 9 1 1 9 2. Add or subtract the fractions, then the whole numbers. + 3 3. Simplify if possible. 5 9 4 In this problem, the denominators are the same, so begin with step 2.

3
**Let’s Do More Examples! Find the sum. 7 8 4 9 4 1 1 4 2 1 3 3 5 3 = =**

+ + 8 9 X 2 X 3 1 8 9 8 7 9 9 = 1 4 1 8 10 Add the whole numbers.

4
**Subtracting Mixed Numbers**

Find the Difference. X 6 3 4 18 7 8 17 20 = 10 3 1 24 X 6 1 8 1 8 1 6 X 4 3 5 X 4 12 4 = 4 = 1 1 - - - 24 20 X 4 X 4 6 8 3 4 5 20 1 4 14 24 7 12 = 6 = 2 = 3 4 7 12 6 2

5
**Now You Try! Find the sum or difference. 3 5 10 6 5 6 10 3 = 4 = 12 10**

X 2 10 6 5 6 10 3 = 4 = 12 X 2 9 10 1 12 7 1 + - 15 10 5 10 1 2 3 4 9 12 10 = 1 = 3 = 1 2 3 4 11 3
