Answer 1

8/15 . 9/9 = 8/5 . 3/9 = 8/5 . 1/3 = 8 . 1 / 5 . 3 = 8 / 15

1/9 . 3/7 = 1/3 . 1/7 = 1 . 1 / 3 . 7 = 1 / 21

2/5 . 7/2 = 1/5 . 7/1 = 1 . 7/ 5 . 1 = 7/5

7/10 . 2/4 = 7/5 . 1/4 = 7 . 1/ 5.4 = 7/20

2/6 . 4 = 2/6 . 4/1 = 1/3 . 4/1 = 1 . 4/ 1 . 3 = 4/3

80 . 13/16 = 80/1 . 13/16 = 5/1 . 13/1 = 5 . 13/ 1 . 1 = 65/1
