Пошаговое объяснение:

======================================

1. в) 4/9 + 1/6 = 8/18 + 3/18 = 11/18

г) 7/15 + 3/40 = 56/120 + 9/120 = 65/120 = 13/24

======================================

2. в) 7/12 - 3/8 = 14/24 - 9/24 = 5/24

г) 9/14 - 19/35 = 45/70 - 38/70 = 7/70 = 1/10

======================================

3. б) 3 11/20 + 2 19/30 = 3 33/60 + 2 38/60 = 5 71/60 = 6 11/60

в) 9 5/6 - 2 3/4 = 9 10/12 - 2 9/12 = 7 1/12

г) 3 3/10 - 1 7/15 = 3 9/30 - 1 14/30 = 2 39/30 - 1 14/30 = 1 25/30 = 1 5/6
