1)32*(2 3/4+1 5/16) 2)24*(2 5/8*1 2/3)
3)16*(8 3/4+2 5/16)
4)30*(2 2/15+1 5/6)
5)26*(1 3/13+2 11/26)

Пошаговое объяснение:

1.

1) 2. 3/4 + 1. 5/16 =

2. 12/16 + 1. 5/16 = 3. 15/16

2) 32 * 3. 15/16 = 32 * 63/16 = 2 * 63/1 = 126/1 = 126

ответ: 126

2.

1) 2. 5/8 * 1. 2/3 = 21/8 * 5/3 = 7/8 * 5/1 = 35/8

2) 24 * 35/8 = 3 * 35/1 = 105/1 = 105

ответ: 105

3.

1) 8. 3/4 + 2. 5/16 =

8. 12/16 + 2. 5/16 = 10. 17/16 = 11. 1/16

2) 16 * 11. 1/16 = 16 * 177/16 = 1 * 177/1 = 177/1 = 177

ответ: 177

4.

1) 2. 2/15 + 1. 5/6 =

2. 4/30 + 1. 25/30 = 3. 29/30

2) 30 * 3. 29/30 = 30 * 119/30 = 1 * 119/1 = 119/1 = 119

ответ: 119

5.

1) 1. 3/13 + 2. 11/26 =

1. 6/26 + 2. 11/26 = 3. 17/26

2) 26 * 3. 17/26 = 26 * 95/26 = 1 * 95/1 = 95/1 = 95

ответ: 95
