Answer 3

1. 8 14/17 + 13/17 = 8 14/17 + 13/17 = 8 + 13 = 21

2. 9 20/23 + 3 18/23 = (9 + 3) + (20/23 + 18/23) = 12 + 38/23 = 12 15/23

3. 18 2/13 – 2 7/13 = (18 – 2) + (2/13 – 7/13) = 16 - 5/13 = 15 8/13

4. 12 5/11 – 8 10/11 = (12 - 8) + (5/11 - 10/11) = 4 - 5/11 = 3 6/11

5. 9 1/13 – 4 10/13 = (9 - 4) + (1/13 - 10/13) = 5 - 9/13 = 4 4/13

6. 5 2/29 – 17/29 = 5 - 17/29 = 4 12/29
