Answer 2

1. 5 5/6 x 2 4/5 = 16

35/6 x 14/5= 49/3 = 16 1/3

2. 2/3 divided 3/5 = 1 1/9 or 2/5?

2/3 x 5/3 = 10/9 = 1 1/9

3. 7/12 divided 2/3 = 7/8
7/12 x 3/2 = 21/24 = 7/8

4. 3 1/2 divided 3/4 = 4 2/3 or 2 5/7
7/2 x 4/3 = 28/6 = 4 2/3

5. 4 2/3 divided 7 = 2/3
14/3 x 1/7 = 14/21 = 2/3

6. 4 1/5 divided 1 2/5 = 3
21/5 x 5/7 = 105/35 = 3

7. 2/5 x 5/14 = 1//7
10/70 = 1/7

8. 2/3 + 1/7 = 17/21 OR 12/21

14/21 + 3/21 = 17/21
