Answer 1

1 i 3/10 - 1/5 = 1 i 3/10 - 2/10 = 1 i 1/10
2/3 + 1/5 = 10/15 + 3/15 = 13/15
4/7 + 1/2 = 8/14 + 7/14 = 15/14 = 1 i 1/14
2 i 2/5 + 3 i 1/2 = 2 i 4/10 + 3 i 5/10 = 5 i 9/10
4 i 3/7 + 2 i 2/3 = 4 i 9/21 + 2 i 14/21 = 6 i 23/21 = 7 i 2/21
4/5 - 2/3 = 12/15 - 10/15 = 2/15
5/7 - 1/4 = 20/28 - 7/28 = 13/28
2 i 3/8 - 1 i 1/6 = 2 i 9/24 - 1 i 4/24 = 1 i 5/24
4 i 1/2 - 2 i 3/5 = 4 i 5/10 - 2 i 6/10 = 3 i 15/10 - 2 i 6/10 = 1 i 9/10
4 i 1/4 - 2 i 2/3 = 4 i 3/12 - 2 i 8/12 = 3 i 15/12 - 2 i 8/12 = 1 i 7/12
5 i 1/9 - 1 i 5/6 = 5 i 2/18 - 1 i 15/18 = 4 i 20/18 - 1 i 15/18 = 3 i 5/18
2 i 1/15 - 1/10= 2 i 2/30 - 3/30 = 1 i 32/30 - 3/30 = 1 i 29/30
5 i 5/13 - 3 i 1/2 = 5 i 10/26 - 3 i 13/26 = 4 i 36/26 - 3 i 13/26 = 1 i 23/26
