Question

8/11 + 7/11
5/9 - 2/9
54/68 - 54/68
107/111 + 49/111
34/41 - 20/41 + 16/41
8/23 + 5/23 - 7/23​

Answer 1

Пошаговое объяснение:

8/11 + 7/11 = (8+7)/11 = 15/11 = 1 4/11

5/9 - 2/9 = (5-2)/9 = 3/9 = 1/3

54/68 - 54/68 = 0

107/111 + 49/111 = (107+49)/111 = 156/111 = 52/37 = 1 15/37

34/41 - 20/41 + 16/41 = (34-20+16)/41 = 30/41

8/23 + 5/23 - 7/23 = (8+5-7)/23 = 6/23
