Пошаговое объяснение:

1. 4 12/35 + 7 11/14 = 4 24/70 + 7 55/70 = 11 79/70 = 12 9/70

2. 9 8/15 + 7 11/12 = 9 32/60 + 7 55/60 = 16 87/60 = 17 27/60 = 17 9/20

3. 14 7/18 - 11 11/12 = 14 14/36 - 11 33/36 = 13 50/36 - 11 33/36 = 2 17/36

4. 4 3/16 - 3 7/24 = 4 9/48 - 3 14/48 = 3 57/48 - 3 14/48 = 43/48
