Пошаговое объяснение:

№1

5 5/9+ 2 1/18 = 5 10/18 + 2 1/18 = 7 11/18

5 7/24 - 3 11/36 = 5 21/72 - 3 22/72 = 4 93/72 - 3 22/72 = 1 71/72

№2

1 1/6 * 3 3/7 = 7/6 * 24/7 = 4

2 4/11 : 2 11/14 = 26/11 : 39/14 = 26/11 * 14/39 = 28/33

№3

4 : 4 4/5 + 2 2/7 * 5 1/4 - 7 11/12= 4 11/12

1) 4 : 4 4/5 = 4 : 24/5 = 4 * 5/24 = 5/6

2) 2 2/7 * 5 1/4 = 16/7 * 21/4 = 12

3) 5/6 + 12 = 12 5/6

4) 12 5/6 - 7 11/12 = 12 10/12 - 7 11/12 = 11 22/12 - 7 11/12 = 4 11/12
