Пошаговое объяснение:

4.

1) 35/64 : 2,5 =

35/64 : 2. 5/10 =

35/64 : 25/10 = 35/64 * 10/25 = 7/32 * 5/5 =

7/32 * 1 = 7/32

2) 2. 3/16 : 7/32 =

35/16 : 7/32 = 35/16 * 32/7 = 5/1 * 2/1 = 10/1 = 10

3) 16 : 32 = 16/32 = 1/2

4) 10 : 1/2 = 10 * 2/1 = 20/1 = 20

5) 1/11 * 0,825 =

1/11 * 825/1000 = 1/11 * 33/40 = 1/1 * 3/40 = 3/40

6) 20 * 3/40 = 60/40 =

3/2 = 1. 1/2

Ответ: 1. 1/2

5.

1) 4,8 * 5/12 = 4. 8/10 * 5/12 = 48/10 * 5/12 = 4/2 * 1/1 = 4/2 = 2

2) 2 * 23/60 = 1 * 23/30 = 23/30

3) 23/30 : 2,3 = 23/30 :

2. 3/10 = 23/30 : 23/10 =

23/30 * 10/23 = 10/30 = 1/3

4) 1. 1/6 : 1/3 = 7/6 : 1/3 =

7/6 * 3/1 = 21/6 = 7/2 = 3,5

5) 21 : 3,5 = 6

6) 6 : 5 = 6/5 = 1. 1/5 или 1,2

Ответ: 1. 1/5
