8. Вычисли. 40·2:80= 60:20·30= 20·3:10= 90:30·20= 5·20:50= 3·30:10= 20:10·40= 50·2:10= 80:40·30= 4·20:80=

Решение:

Давай решим эти примеры по порядку:

1. 40 ⋅ 2 : 80 = 80 : 80 = 1

2. 60 : 20 ⋅ 30 = 3 ⋅ 30 = 90

3. 20 ⋅ 3 : 10 = 60 : 10 = 6

4. 90 : 30 ⋅ 20 = 3 ⋅ 20 = 60

5. 5 ⋅ 20 : 50 = 100 : 50 = 2

6. 3 ⋅ 30 : 10 = 90 : 10 = 9

7. 20 : 10 ⋅ 40 = 2 ⋅ 40 = 80

8. 50 ⋅ 2 : 10 = 100 : 10 = 10

9. 80 : 40 ⋅ 30 = 2 ⋅ 30 = 60

10. 4 ⋅ 20 : 80 = 80 : 80 = 1

Ответ: 1, 90, 6, 60, 2, 9, 80, 10, 60, 1

Ты молодец! У тебя всё получится!
