6 i 3/10 + 1 i 1/2 = 6 i 3/10 + 1 i 5/10 = 7 i 8/10 = 7 i 4/5
5 i 1/8 + 7 i 13/24 = 5 i 3/24 + 7 i 13/24 = 12 i 16/24 = 12 i 2/3
2 i 1/2 + 5 i 2/3 = 2 i 3/6 + 5 i 4/6 = 7 i 7/6 = 8 i 1/6
7 i 8/15 - 5 i 7/10 = 7 i 16/30 - 5 i 21/30 = 6 i 46/30 - 5 i 21/30 = 1 i 25/30 = 1 i 5/6
5 i 11/15 - 3 i 5/6 = 5 i 22/30 - 3 i 25/30 = 4 i 52/30 - 3 i 25/30 = 1 i 27/30
