Answer 1

Пошаговое объяснение:

№1

1) 3. 3/4 * 3/4 = 15/4 * 3/4 = 45/16 = 2. 13/16

2) 8. 4/9 : 3. 4/5 = 76/9 : 19/5 = 76/9 * 5/19 = 4/9 * 5/1 = 20/9 = 2. 2/9

3) 1. 1/2 : 27 = 3/2 * 1/27 = 1/2 * 1/9 = 1/18

4) 2. 13/16 - 2. 2/9 = 2. 117/144 - 2. 32/144 = 85/144

5) 85/144 + 1/18 = 85/144 + 8/144 = 93/144 = 31/48

6) 31/48 : 1. 29/48 = 31/48 : 77/48 = 31/48 * 48/77 = 31/77

№2

1) 2. 5/14 * 4. 2/3 = 33/14 * 14/3 = 33/3 = 11

2) 12 : 2. 1/4 = 12 : 9/4 = 12 * 4/9 = 4 * 4/3 = 16/3 = 5. 1/3

3) 11 - 5. 1/4 = 10. 4/4 - 5. 1/4 = 5. 3/4

4) 5. 3/4 + 5. 1/3 = 5. 9/12 + 5. 4/12 = 10. 13/12 = 11. 1/12

5) 9. 7/18 - 2. 5/9 = 9. 7/18 - 2. 10/18 = 8. 25/18 - 2. 10/18 = 6. 15/18 = 6. 5/6

6) 11. 1/12 : 6. 5/6 = 133/12 : 41/6 = 133/12 * 6/41 = 133/2 * 1/41 = 133/82 = 1. 51/82
