7 i 3/5 + 1 i 4/9 = 7 i 27/45 + 1 i 20/45 = 8 i 47/45 = 9 i 2/45

3 i 3/10 + 7 i 5/6 = 3 i 9/30 + 7 i 25/30 = 10 i 34/30 = 11 i 4/30

9 i 1/2 + 5 i 3/5 = 9 i 5/10 + 5 i 6/10 = 14 i 11/10 = 15 i 1/10

9 i 4/5 - 3 i 3/4 = 9 i 16/20 - 3 i 15/20 = 6 i 1/20

6 i 1/3 - 2 i 5/9 = 6 i 3/9 - 2 i 5/9 = 5 i 12/9 - 2 i 5/9 = 3 i 7/9

9 i 6/7 - 1 i 1/11 = 9 i 66/77 - 1 i 7/77 = 8 i 59/77

2 i 2/5 * 1 i 3/7 = 12/5 * 10/7 = 24/7 = 3 i 3/7  skr 10 i 5 przez 5

4 i 1/3 * 2 i 2/5 = 13/3 * 12/5 = 156/15 = 10 i 6/15 = 10 i 2/5

1 i 2/9 * 1 i 4/7 = 12/9 * 11/7 = 132/63 = 2 i 6/63
