Answer 1

1/26 + 5/78 = 4/39
1/32 + 5/96 = 7/84
1/32 + 7/96 = 5/48
1/78 + 4/39 = 6/52
1/96 + 7/48 = 5/32
2/68 + 9/34 = 5/17
2/68 + 9/51 = 7/34
4/39 + 1/78 = 6/52
4/56 + 7/98 = 3/21
5/26 + 9/78 = 4/13
5/78 + 1/26 = 4/39
5/96 + 1/32 = 7/84
6/34 + 8/51 = 9/27
7/48 + 1/96 = 5/32
7/96 + 1/32 = 5/48
7/98 + 4/56 = 3/21
8/51 + 6/34 = 9/27
9/34 + 2/68 = 5/17
9/51 + 2/68 = 7/34
9/78 + 5/26 = 4/13
