2/3 + 2/9 = 6/9 + 2/9 = 8/9
3/4 + 5/12 = 9/12 + 5/12 = 14/12 = 1 i 2/12 = 1 i 1/6
2 i 1/3 + 1 i 7/15 = 2 i 5/15 + 1 i 7/15 = 3 i 12/15 = 3 i 4/5
1 i 3/5 + 5 i 4/7 = 1 i 21/35 + 5 i 20/35 = 6 i 41/35 = 7 i 6/35
4 i 9/14 + 2 i 11/21 = 4 i 27/42 + 2 i 22/21 = 6 i 49/21 = 8 i 7/21 = 8 i 1/3
3 i 1/12 + 1 i 5/18 = 3 i 3/36 + 1 i 10/36 = 4 i 13/36
