Пошаговое объяснение:

№1

3 2/9 * 1 3/5 + 1 3/5 * 6 7/9 =

1 3/5 * (3 2/9 + 6 7/9) = 1 3/5 * 9 9/9 =

8/5 * 10 = 80/5 = 16

№2

4 7/9 * 1 1/11 - 3 5/9 * 1 1/11 =

1 1/11 * (4 7/9 - 3 5/9) = 1 1/11 * 1 2/9 =

12/11 * 11/9 = 12/9 = 4/3 = 1 1/3

№3

3 2/3 * 3 = 11/3 * 3 = 33/3 = 11

№4

(2 1/4 - 5/8) * 4 = 2 1/4 * 4 - 5/8 * 4 =

9/4 * 4 - 20/8 = 9 - 2 4/8 = 8 8/8 - 2 4/8 =

6 4/8 = 6 1/2
