8/10 + 3 i 3/2 = 8/10 + 9/2 = 8/10 + 45/10 = 53/10 = 5 i 3/10
2 i 3/5 + 2 i 4/7 = 13/5 + 18/7 = 91/35 + 90/35 = 181/35 = 5 i 6/35
13/10 + 2/5 = 13/10 + 4/10 = 17/10 = 1 i 7/10
8/7 + 3/7 = 11/7 = 1 i 4/7
4/5 + 8/9 = 36/45 + 40/45 = 76/45 = 1 i 31/45
3 i 3/5 + 4 i 4/6 = 18/5 + 28/6 = 108/30 + 140/30 = 148/30 = 4 i 28/30 = 4 i 14/15
4 i 6/5 + 1 i 1/10 = 26/5 + 11/10 = 52/10 + 11/10 = 63/10 = 6 i 3/10
