Помогите пожалуйста баллы дам !​

Answer 1

Пошаговое объяснение:

№1

8 1/4 - 3 5/12 - 11/18 = 8 9/36 - 3 15/36 - 22/36 =

7 45/36 - 3 15/36 - 22/36 = 4 30/36 - 22/36 = 4 8/36 = 4 2/9

№2

7 5/48 - 4 7/32 - 15/16 = 7 10/96 - 4 21/96 - 90/96 =

6 106/96 - 4 21/96 - 90/96 = 2 85/96 - 90/96 =

1 181/96 - 90/96 = 1 91/96

№3

1 1/13 + 4 3/8 - 2 11/26 =

1 8/104 + 4 39/104 - 2 44/104 =

5 47/104 - 2 44/104 = 3 3/104

№4

12 1/66 + 1 1/6 - 2 = 12 1/66 + 1 11/66 - 2 =

13 12/66 - 2 = 13 2/11 - 2 = 11 2/11

№5

3 3/50 - 2 1/20 + 1 3/40 =

3 12/200 - 2 10/200 + 1 15/200 =

1 2/200 + 1 15/200 = 2 17/200
