Answer 1

Ответ:

11/20

Пошаговое объяснение:

1) 2 - 1/9 = 1 9/9 - 1/9 = 1 8/9

2) 1 8/9 + 3/4 = 1 32/36 + 27/36 = 1 59/36 = 2 23/36

3) 3/5 + 2/3 = 9/15 + 10/15 = 19/15 = 1 4/15

4) 1 4/15 - 1/15 = 1 3/15 = 1 1/5

5) -2/9 + 1 = -2/9 + 9/9 = 7/9

6) 7/9 - 5/3 = 7/9 - 15/9 = -8/9

7) 2 23/36 - 1 1/5 = 2 115/180 - 1 36/180 = 1 79/180

8) 1 79/180 + (-8/9) = 1 79/180 - 8/9 = 1 79/180 - 160/180 = 259/180 - 160/180 = 99/180 = 11/20
