1/7 + 5/14 = 2/14 + 5/14 = 7/14 = 1/2
3/4 + 5/12 = 9/12 + 5/12 = 14/12 = 1 i 2/12 = 1 i 1/6
8/9 - 5/18 = 16/18 - 5/18 = 11/18
1/3 + 3/4 = 4/12 + 9/12 = 13/12 = 1 i 1/12
3/5 - 1/2 = 6/10 - 5/10 = 1/10
1 i 1/2 - 1/3 = 1 i 3/6 - 2/6 = 1 i 1/6
1 i 1/2 + 3/8 = 1 i 4/8 + 3/8 = 1 i 7/8
1 i 1/3 - 2/9 = 1 i 3/9 - 2/9 = 1 i 1/9
2 i 3/5 - 7/10 = 2 i 6/10 - 7/10 = 1 i 16/10 - 7/10 = 1 i 9/10
5/6 - 1/4 = 10/12 - 3/12 = 7/12
1 i 1/6 - 7/9 = 1 i 3/18 - 14/18 = 21/18 - 14/18 = 7/18
2 i 3/8 - 1 i 5/6 = 2 i 9/24 - 1 i 20/24 = 1 i 33/24 - 1 i 20/24 = 13/24
