1 i 5/6 + 1/2 = 1 i 5/6 + 3/6 = 1 i 8/6 = 2 i 2/6 = 2 i 1/3

1 i 5/6 + 2/3 = 1 i 5/6 + 4/6 = 1 i 9/6 = 2 i 3/6 = 2 i 1/2

1 i 5/6 + 2 i 1/12 = 1 i 10/12 + 2 i 1/12 = 3 i 11/12

1 i 5/6 + 1 i 3/4 = 1 i 10/12 + 1 i 9/12 = 2 i 19/12 = 3 i 7/12

1 i 5/6 + 1 i 1/5 = 1 i 25/30 + 1 i 6/30 = 2 i 31/30 = 3 i 1/30

1 i 5/6 + 2 i 7/8 = 1 i 20/24 + 2 i 21/24 = 3 i 41/24 = 4 i 17/24

1 i 5/6 + 3 i 4/9 = 1 i 15/18 + 3 i 8/18 = 4 i 23/18 = 5 i 5/18

1 i 9/10 - 3/5 = 1 i 9/10 - 6/10 = 1 i 3/10

2 i 1/15 - 3/5 = 2 i 1/15 - 9/15 = 1 i 16/15 - 9/15 = 1 i 7/15

1 i 1/3 - 3/5 = 1 i 5/15 - 9/15 = 20/15 - 9/15 = 11/15

3/4 - 3/5 = 15/20 - 12/20 = 3/20

4 i 1/2 - 3/5 = 4 i 5/10 - 6/10 = 3 i 15/10 - 6/10 = 3 i 9/10

5 i 7/20 - 3/5 = 5 i 7/20 - 12/20 = 4 i 27/20 - 12/20 = 4 i 15/20 = 4 i 3/4

1 i 3/7 - 3/5 = 1 i 15/35 - 21/35 = 50/35 - 21/35 = 29/35
