помогите пожалуйста

​

Answer 1

Пошаговое объяснение:

1) 3 * 7/22 = 21/22

2) 5 * 31/33 = 155/33

3) 155/33 : 4 = 155/33 * 1/4 = 155/132 = 1 23/132

4) 1/5 * 2 = 2/5

5) 2/5 * 33/51 = 66/255

6) 66/255 * 12 = 66/85 * 4 = 264/85

7) 264/85 * 3/10 = 132/85 * 3/5 = 396/425

8) 5 - 21/22 = 4 22/22 - 21/22 = 4 1/22

9) 4 1/22 + 1 23/132 = 4 6/132 + 1 23/132 = 5 138/132 = 6 6/132 = 6 1/22

10) 6 1/22 + 396/425 = 133/22 + 396/425 = 65237/9350 = 6 9137/9350
