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

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

4 i 4/5 : 1 i 7/9 = 24/5 : 16/9 = 24/5 * 9/16 = 27/10 = 2 i 7/10

6 i 3/4 : 1 i 1/8 = 27/4 : 9/8 = 27/4 * 8/9 = 6

2 i 5/6 : 12 i 3/4 = 17/6 : 51/4 = 17/6 * 4/51 = 2/9

5 i 1/7 : 2 i 2/21 = 36/7 : 44/21 = 36/7 * 21/44 = 54/22 = 2 i 10/22 = 2 i 5/11

3 i 1/5 : 1 i 1/3 : 4 i 4/5 = 16/5 : 4/3 : 24/5 = 16/5 * 3/4 * 5/24 = 12/5 * 5/24 = 1/2
