Question

Помогите с математикой 5 класс

Answer 1

Пошаговое объяснение:

№1

1) 2 3/8 + 3 5/12 = 2 9/24 + 3 10/24 = 5 19/24

2) 6 3/16 - 5 19/24 = 6 9/48 - 5 38/48 = 5 57/48 - 5 38/48 = 19/48

№2

1 - 1 7/8 = -(1 7/8 - 1) = -7/8

№3

4 + 3 3/7 = 7 3/7

1 11/16 - 1 = 11/16

1 2/7 + 2 1/7 = 3 3/7

3 - 1 7/8 = 2 8/8 - 1 7/8 = 1 1/8

12 7/12 + 3 8/9 = 12 21/36 + 2 32/36 = 14 53/36 = 15 17/36

8 2/3 - 2 5/7 = 8 14/21 - 2 15/21 = 7 35/21 - 2 15/21 = 5 20/21
