Answer 2

2 : 2/5 = 2/1 x 5/2 = 5

6 : 9/10 = 6/1 x 10/9 = 20/3 = 6  2/3

3 : 1/2 = 3/1 x 2/1 = 6

10 : 3  1/3 = 10/1 : 10/3 = 10/1 x 3/10 = 3

1/2 : 3/4 = 1/2 x 4/3 = 2/3

4/5 : 6/7 = 4/5 x 7/6 = 14/15

5/8 : 3/10 = 5/8 x 10/3 = 25/20 = 1  5/20 = 2  1/12

4/9 : 5/6 = 4/9 x 6/5 = 8/15

5/7 : 1  2/5 = 5/7 : 7/5 = 5/7 x 5/7 = 25/49

2  2/5 : 4/9 = 12/5 x 9/4 = 27/5 = 5  2/5

3/4 : 1  1/8 = 3/4 : 9/8 = 3/4 x 8/9 = 2/3

4  2/3 : 7/8 = 14/3 x 8/7 = 16/3 = 5  1/3
