Answer 1

8 i3/4 - 3i 1/6 = 8 i 9/12 - 3 i 2/12= 5 i 7/12

40 - 9 i3/8 = 39 i 8/8 - 9 i 3/8 = 30 i 5/8

7 i5/6 - 2 i3/8 = 7 i 20/24 - 2 i 9/24 = 5 i 11/24

2 i8/9 + 5 i5/6 = 2 i 16/18 + 5 i 15/18 = 7 i 31/18 = 8 i 13/18

4/25 + 2/15 = 12/75 + 10/75 = 22/75

9 i3/4 - 3 i7/8 = 9 i6/8 - 3 i7/8 = 8 i 14/8 - 3 i7/8 = 5 i 7/8

8 i2/3 - 3i4/5 = 8 i 10/15 - 3 i12/15 = 7i 25/15 - 3 i12/15 = 4 i 13/15

11 i1/2 -1 i3/6 = 11 i 3/6 -1 i3/6 = 10

3/7 + 5/9 = 27/63 + 35/63 = 62/63

9 i2/3+ 2 i3/4 = 9 i 8/12 + 2 i 9/12 = 11 i 17/12 = 12 i 5/12

9 i2/4 - 5 i1/2 = 9 i2/4 - 5 i 2/4 = 4

2/9 + 1/12 = 8/36 + 3/36 = 11/36

1 i4/7 + 4 i5/8 = 1 i 32/56 + 4 i 35/56 = 5 i 67/56 = 6 i 11/56

5 i5/6 + 6i 7/8 = 5 i 20/24 + 6 i 21/24 = 11 i 41/24 = 12 i 17/24

1/4 - 7/36 = 9/36 - 7/36 = 2/36
