1. Adding Mixed Numbers Lesson 5-3:

2. Example #1: 6 3 + 7 12 1 8 9 3 2 9 =

3. Example #2: 2 4 + 3 7 6767 7 9 6

4. Now, Simplify 7 9 6 7 9 1 7 2 6+ 1 2 7 = 7 2 7

5. Process: 1.Separate the whole number parts from the fraction parts. 2.Find common denominators for the fractions and then add them. 3. Add the whole numbers together. 4. Simplify.

6. Example #3: 9 3 + 3 4 5 6 9 3 The LCM of 4 and 6 is 12. 12 9 10 12 19 12

7. Now, Simplify 12 19 12 19 1 12 7 + 1 7 =13 7 12

8. Example #4: 3 1 + 2 3 3 4 3 1 12 8 9 17 4 The LCM of 3 and 4 is 12.

9. Now, Simplify 12 17 4 12 17 1 12 5 4+ 1 5 = 5 5
