Answer 1

Пошаговое объяснение:

1) 3/4 + 5/7 = 21/28 + 20/28 = 41/28 = 1 13/28

2) 9/14 - 3/4 = 18/28 - 21/28 = -3/28

3) 11/12 - 2/3 = 11/12 - 8/12 = 3/12 = 1/4

4) 7/25 + 4/10 = 14/50 + 20/50 = 34/50 = 17/25

5) 11/18 - 5/12 = 44/72 - 30/72 = 14/72 = 7/36

6) 13/18 + 7/15 = 65/90 + 42/90 = 107/90 = 1 17/90

7) 19/24 - 25/36 = 57/72 - 50/72 = 7/72

8) 5/6 - 3/4 + 5/24 = 20/24 - 18/24 + 5/24 = (20-18+5)/24 = 7/24

9) 5/8 + 11/28 - 9/14 = 35/56 + 22/56 - 36/56 = (35+22-36)/56 = 21/56 = 3/8
