Answer 1

4 - 7/15 = 3 i 15/15 - 7/15 = 3 i 8/15
spr  3 i 8/15 + 7/15 = 3 i 15/15 = 4

2 - 4/7 = 1 i 7/7 - 4/7 = 1 i 3/7
spr  1 i 3/7 + 4/7 = 1 i 7/7 = 2

6 - 5/12 = 5 i 12/12 - 5/12 = 5 i 7/12
spr  5 i 7/12 + 5/12 = 5 i 12/12 = 6

14 i 1/6 - 5 i 2/6 = 13 i 7/6 - 5 i 2/6 = 8 i 5/6
spr  8 i 5/6 + 5 i 2/6 = 13 i 7/6 = 14 i 1/6

9 i 2/7 - 3 i 5/7 = 8 i 9/7 - 3 i 5/7 = 5 i 4/7
spr  5 i 4/7 + 3 i 5/7 = 8 i 9/7 = 9 i 2/7
