Answer 1

Пошаговое объяснение:

1) 9/11 - 2/5 = 45/55 - 22/55 = 23/55

2) 13/16 - 9/32 = 26/32 - 9/32 = 17/32

3) 3/28 + 5/14 = 3/28 + 10/28 = 13/28

4) 14/15 - 7/10 = 28/30 - 21/30 = 7/30

5) 3/8 + 1/6 = 9/24 + 4/24 = 13/24

6) 9/25 - 7/20 = 36/100 - 35/100 = 1/100

7) 37/42 - 17/24 = 148/168 - 119/168 = 29/168

8) 11/24 - 3/16 = 22/48 - 9/48 = 13/48

9) 9/16 + 7/24 - 3/8 = 27/48 + 14/48 - 18/48 = (27+14-18)/48 = 23/48
