Answer:

2. 10 / 22

3. 11.15

4. 7 / 9

5. 11 / 35

6. -11 / -20

7. 18 / -3

8. -23 / -6

9. 985 / 25

Step-by-step explanation:

1. 8 / 8 - 5 / 8 = 3 / 8

2. 6 / 16 + 4 / 6 = 10 / 22

3. 8 / 15 + 3 / 15 = 11 / 15

4. 10 / 18 - 3 / 9 = 7 / 9

5. 4 / 20 + 7 / 15 = 11 / 35

6. 4 / 5 - 15 / 25 = -11 / -20

7. 53 / 3 - 35 / 6 = 18 / -3

8. 32 / 3 - 55 / 9 = -23 / -6

9. 73/10 + 912/15 = 985 / 25
