Помогите пожалуйста математика 5 класс срочно ❗️❗️❗️❗️❗️

Пошаговое объяснение:

12 - 3/4 = 11 4/4 - 3/4 = 11 1/4

11 - 2 3/7 = 10 7/7 - 2 3/7 = 8 4/7

15 - 6 4/9 = 14 9/9 - 6 4/9 = 8 5/9

2 + 3 6/10 = 5 6/10

5 - 10/3 = 5/1 - 10/3 = 15/3 - 10/3 = 5/3 = 1 2/3

13/13 - 1/2 = 26/26 - 13/26 = 13/26 = 1/2

4 - 14/5 = 4/1 - 14/5 = 20/5 - 14/5 = 6/5 = 1 1/5

7 - 3 12/5 = 7 - 27/5 = 7/1 - 27/5 = 35/5 - 27/5 = 8/5 = 1 3/5
