2 1/6-1 5/6
2 1/4-1 3/4
4 1/8-2 7/8

Answer 1

5/8-3/8 =2/8 = 1/4
3/4-1/4 = 2/4 = 1/2
5/6-1/6 = 4/6 = 2/3
6/7-3/7 = 3/7
1 4/5-3/5 = 1 i 1/5
2 1/6-1 5/6 = 1 i 7/6 - 1 i 5/6 = 2/6 = 1/3
2 1/4-1 3/4 = 1 i 5/4 - 1 i 3/4 = 2/4 = 1/2
4 1/8-2 7/8 = 3 i 9/8 - 2 i 7/8 = 1 i 2/8 = 1 i 1/4

3/5 + 1/5 + 2/5 = 6/5 = 1 i 1/5
3/4 + 1/4 + 2/4 = 6/4 = 1 i 2/4 = 1 i 1/2
7/8 - 1/8 - 5/8 = 1/8
3/7 + 5/7 + 4/7 = 12/7 = 1 i 5/7
1 i 1/4 + 2 i 3/4 = 3 i 4/4 = 4
3 i 5/6 - 2 i 1/6 = 1 i 4/6 = 1 i 2/3
4 i 1/10 - 3 i 7/10 = 3 i 11/10 - 3 i 7/10 = 4/10 = 2/5
2 i 4/5 + 5 i 4/5 = 7 i 8/5 = 8 i 3/5
