Пошаговое объяснение:

1) 3/4х = 3/4 * 5 = 15/4 =

3. 3/4

2) 3. 3/4 - 9/16 = 3. 12/16 -

9/16 = 3. 3/16

3) 4/9 * 3. 3/16 = 4/9 * 51/16 = 1/9 * 51/4 = 51/36 = 1. 15/36 = 1. 5/12

4) 2/3х = 2/3 * 5 = 10/3 =

3. 1/3

5) 1. 5/12 + 3. 1/3 = 1. 5/12 + 3. 4/12 = 4. 9/12 = 4. 3/4

6) 4. 3/4 : 9. 1/2 = 19/4 : 19/2 = 19/4 * 2/19 = 2/4 = 1/2

Ответ: 1/2
