Пошаговое объяснение:

1.

9/14 + 14/21 = 27/42 + 28/42 = 55/42 =

1. 13/42

9/14 - 14/21 = 27/42 - 28/42 = -1/42

9/14 < 14/21

2.

1/4 + 1/5 = 5/20 + 4/20 = 9/20

1/4 - 1/5 = 5/20 - 4/20 = 1/20

1/4 > 1/5

3.

5/8 + 1/2 = 5/8 + 4/8 = 9/8 = 1. 1/8

5/8 - 1/2 = 5/8 - 4/8 = 1/2

5/8 > 1/2

4.

3/4 + 1/6 = 9/12 + 2/12 = 11/12

3/4 - 1/6 = 9/12 - 2/12 = 7/12

3/4 > 1/6

5.

1/2 + 5/12 = 6/12 + 5/12 = 11/12

1/2 - 5/12 = 6/12 - 5/12 = 1/12

1/2 > 5/12

6.

9/10 + 9/40 = 36/40 + 9/40 = 45/40 = 1. 5/40 = 1. 1/8

9/10 - 9/40 = 36/40 - 9/40 = 27/40

9/10 > 9/40

7.

7/12 + 1/7 = 49/84 + 12/84 = 61/84

7/12 - 1/7 = 49/84 - 12/84 = 37/84

7/12 > 1/7

8.

8/9 + 1/4 = 32/36 + 9/36 = 41/36 = 1. 5/36

8/9 - 1/4 = 32/36 - 9/36 = 23/36

8/9 > 1/4

9.

7/10 + 4/15 = 21/30 + 8/30 = 29/30

7/10 - 4/15 = 21/30 - 8/30 = 13/30

7/10 > 4/15
