Answer 1

Explicación paso a paso:

1. 9/7

2. 6/5 +1/7 = 42/35 + 5/35 => 47/35

3. 5/3 - 4/9 = 45/27 - 12/27 = 33/27 => 11/9

4. 4/5 - 1/7 = 28/35 - 5/35 => 23/35

5.6/7 +2/3 - 1/4 = 72 + 56 - 21 / 84 = 107 / 84

6. 11/4 +1/4 - 8/3 = 132 + 12 - 128 / 48 = 272/48=>136/24

7. 7/6 + 1/7 - 2/3 = 147 + 18 - 84 / 126 = 249/ 126 => 83/42

8. 5/7 - 1/4 + 8/3 = 60 - 21 + 224/ 84 = 263/84
