Answer 1

Explicación paso a paso:

1/2 + 5/4 = 2/4 + 5/4 = 7/4

4/6 + 7/7 = 28/42 + 42/42 = 70/42 = 5/3

9/3 + 3/7 = 63/21 + 9/21 = 72/21 = 24/7

9/3 + 2/8 = 72/24 + 6/24 = 78/24 = 39/12

2/8 + 2/7 = 14/56 + 16/ 56 = 30/56 = 15/28

2/5 + 7/6 = 12/30 + 42/30 = 54/30 = 9/5

5/3 - 2/8= 40/24 - 6/24 = 32/24 = 4/3

6/7 - 1/9 = 54/63 - 7/63 = 47/63

6/7 - 2/5 = 30/35 - 14/35 = 16/35

2/9 - 2/7 = 14/63 - 18/63 = -4/63

9/2 - 1/5 = 45/10 - 2/10 = 43/10

8/2 - 3/8 = 32/8 - 3/8 = 29/8
