Answer 1

Пошаговое объяснение:

№3

1) 6 5/6 : 1 5/36 = 41/6 : 41/36 = 41/6 * 36/41 = 1/1 * 6/1 = 6/1 = 6

2) 8 5/7 - 6 = 2 5/7

3) 2 5/7 : 4 3/4 = 19/7 : 19/4 = 19/7 * 4/19 = 1/7 * 4/1 = 4/7

№4

1) 2 5/6 + 2 2/9 = 2 15/18 + 2 4/18 = 4 19/18 = 5 1/18

2) 5 1/18 : 3 1/4 = 91/18 : 13/4 = 91/18 * 4/13 = 7/9 * 2/1 = 14/9 = 1 5/9

3) 2/7 : 1 2/7 = 2/7 : 9/7 = 2/7 * 7/9 = 2/1 * 1/9 = 2/9

4) 1 5/9 - 2/9 = 1 3/9 = 1 1/3
