Пошаговое объяснение:

1) (5. 1/2)² = (11/2)² = 121/4

2) 121/4 : 4. 2/5 = 121/4 : 22/5 = 121/4 * 5/22 = 605/88 = 6. 77/88 = 6. 7/8

3) 10 - 6. 7/8 = 9. 8/8 - 6. 7/8 = 3. 1/8

4) 8. 3/4 : 3. 1/8 = 35/4 : 25/8 = 35/4 * 8/25 = 7/1 * 2/5 = 14/5 = 2. 4/5

5) 7. 1/5 : 2. 4/7 = 36/5 : 18/7 = 36/5 * 7/18 = 2/5 * 7/1 = 14/5 = 2. 4/5

6) 3. 1/8 * 2 = 25/8 * 2 = 50/8 = 25/4 = 6. 1/4

7) 8. 1/12 - 1. 5/6 = 8. 1/12 - 1. 10/12 = 7. 13/12 - 1. 10/12 = 6. 3/12 = 6. 1/4

8) 6. 1/4 : 6. 1/4 = 1

9) 2. 4/5 - 2. 4/5 + 1 = 1
