1/2 + 1/8 = 4/8 + 11/8 = 5/8
1/5 + 1/10 = 2/10 + 1/10 = 3/10
1/4 + 1/3 = 3/12 + 4/12 = 7/12
1/2 + 1/7 = 7/14 + 2/14 = 9/14
1/6 + 3/4 = 2/12 + 9/12 = 11/12
1/8 + 5/6 = 3/24 + 20/24 = 23/24
1/2 + 1/6 = 3/6 + 1/6 = 4/6 = 2/3
2/5 + 4/15 = 6/15 + 4/15 = 10/15 = 2/3
5/6 + 3/4 = 10/12 + 9/12 = 19/12 = 1 i 7/12
1/6 + 1/9 = 3/18 + 2/18 = 5/18
1 i 2/3 + 2 i 1/6 = 1 i 4/6 + 2 i 1/6 = 3 i 5/6
2 i 1/2 + 1 i 3/4 = 2 i 2/4 + 1 i 3/4 = 3 i 5/4 = 4 i 1/4
