Помогите пожалуйста срочно!!!
2) 1 1/4 * 2/5 - 1/3
4) 5/6 : 1/3 + 1 3/8
6) 2 1/3 : 1 5/9 - 5/6

Пошаговое объяснение:

2)

1 1/4 * 2/5 - 1/3 = 5/4 * 2/5 - 1/3 =

1/2 * 1/1 - 1/3 = 1/2 - 1/3 = 3/6 - 2/6 = 1/6

4)

5/6 : 1/3 + 1 3/8 = 5/6 * 3/1 + 1 3/8 =

15/6 + 1 3/8 = 2 3/6 + 1 3/8 =

2 12/24 + 1 9/24 = 3 21/24 = 3 7/8

6)

2 1/3 : 1 5/9 - 5/6 = 7/3 : 14/9 - 5/6 =

7/3 * 9/14 - 5/6 = 1/1 * 3/2 - 5/6 =

3/2 - 5/6 = 9/6 - 5/6 = 4/6 = 2/3
