Пошаговое объяснение:

1) 3/4 + 2/3 = 9/12 + 8/12 = 17/12 = 1 5/12

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

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

4) 7/15 + 3/40 = 56/120 + 9/120 = 65/120 = 13/24

5) 6/7 - 2/3 = 18/21 - 14/21 = 4/21

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

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

8) 9/14 - 19/35 = 45/70 - 38/70 = 7/70 = 1/10

9) 0,75 + 1/3 = 75/100 + 1/3 = 3/4 + 1/3 = 9/12 + 4/12 = 13/12 = 1 1/12

10) 1,95 + 3/5 = 1,95 + 0,6 = 2,55
