Надо сделать 5 задание 1 и 2

Пошаговое объяснение:

1) 1 1/2 + 2 2/3 = 1 3/6 + 2 4/6 = 3 7/6 = 4 1/6

2) 4 1/6 + 3 3/4 = 4 2/12 + 3 9/12 = 7 11/12

3) 7 11/12 * 3 3/5 = 95/12 * 18/5 = 57/2

4) 15 1/8 : 2 1/5 = 121/8 : 11/5 = 121/8 * 5/11 = 55/8 = 6 7/8

5) 14 - 6 7/8 = 7 1/8

6) 57/2 : 7 1/8 = 57/2 : 57/8 = 57/2 * 8/57 = 4

ответ: 4

1) 5 1/7 * 7 = 36/7 * 7 = 36

2) 4 1/12 * 36 = 49/12 * 36 = 49 * 3 = 147

3) 8 6/7 * 147 = 62/7 * 147 = 62 * 21 = 1302

4) 7 2/3 * 1302 = 23/3 * 1302 = 23 * 434 = 9982

5) 6 1/4 * 7 1/5 = 25/4 * 36/5 = 5 * 9 = 45

6) 1 2/5 * 45 = 7/5 * 45 = 7 * 9 = 63

7) 3 4/9 * 63 = 31/9 * 63 = 31 * 7 = 217

8) 5 3/4 * 217 = 23/4 * 217 = 4991/4

9) 9982 : 4991/4 = 9982 * 4/4991 = 2 * 4 = 8

ответ: 8
