7/8 : 1 i 5/16 = 7/8 : 21/16 = 7/8 * 16/21 = 2/3

2/9 : 2 i 2/3 = 2/9 : 8/3 = 2/9 * 3/8 = 1/12

3 i 1/3 : 1 i 1/3 = 10/3 : 4/3 = 10/3 * 3/4 = 5/2 = 2 i 1/2

7 i 1/5 : 1 i 1/5 = 36/5 : 6/5 = 36/5 * 5/6 = 6

2 i 3/4 : 4 i 2/5 = 11/4 : 22/5 = 11/4 * 5/22 = 5/8

1 i 5/12 : 1 i 7/10 = 17/12 : 17/10 = 17/12 * 10/17 = 5/6
