2) 3/6 или 1/3

3) 1 целая 9/16

2) 1/6 + 1/3 = 1/6 + 2/6 = 3/6

1 - 3/6= 3/6 = 1/2

Ответ: 1/2

3) (55 * 1/33) * (6 : 1/2) / (2 1/3 : 3 1/2 * 1 3/5)

1.  55 * 1/33 = 55/33

2. 6 : 1/2 = 6 * 2/1 = 12

3. 7/3 : 7/2 = 14/21 = 2/3

4. 2/3 * 8/5 = 16/15 = 1 1/15

5. 55/33 * 12 = 660/33 = 20

6. 20 : 16/15 = 20 * 15/16 = 300/16 = 18 12/16 = 18 3/4

Ответ: 18 3/4
