Ответ:

Пошаговое объяснение:

2/3 +3/5 = 10/15 + 9/15 = 19/15 = 1ц. 4/15

4/9+1/6 = 8/18 + 3/18 = 11/18

1/18+5/12 = 2/36 + 15/36 = 17/36

3/10+2/15 = 9/30 + 4/30 = 13/30

6/7-2/3 = 18/21 - 14/21 = 4/21

11/12-5/6 = 11/12 - 10/12 = 1/12

7/12-3/8 = 14/24 - 9/24 = 5/24

9/14-17/35 = 45/70 - 34/70 = 11/70
