2 i 2/3 : 4/7 = 8/3 : 4/7 = 8/3 * 7/4 = 56/12 = 4 i 8/12 = 4 i 2/3
2 i 1/4 : 4/5 = 9/4 : 4/5 = 9/4 * 5/4 = 45/16 = 2 i 13/16
3 i 4/5 : 2/3 = 19/5 : 2/3 = 19/5 * 3/2 = 57/10 = 5 i 7/10
3 i 1/2 : 2 i 2/5 = 7/2 : 12/5 = 7/2 * 5/12 = 35/24 = 1 i 11/24
3/4 : 1 i 2/3 = 3/4 : 5/3 = 3/4 * 3/5 = 9/20
9/10 : 2 i 3/4 = 9/10 : 11/4 = 9/10 * 4/11 = 36/110 = 18/55
