Answer 1

Пошаговое объяснение:

1) 17/36 * 9/34 = 1/4 * 1/2 = 1/8

2) 2 7/16 * 8 = 39/16 * 8 = 39/2 * 1 = 39/2 = 19 1/2

3) 1 3/4 * 2 1/7 = 7/4 * 15/7 = 1/4 * 15/1 = 15/4 = 3 3/4

4) 9/16 : 21/24 = 9/16 * 24/21 = 3/2 * 3/7 = 9/14

5) 2 1/3 : 21 = 7/3 * 1/21 = 1/3 * 1/3 = 1/9

6) 1 2/3 : 3 5/6 = 5/3 : 23/6 = 5/3 * 6/23 = 5/1 * 2/23 = 10/23

7)

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

2) 6 * 1 1/6 = 6 * 7/6 = 42/6 = 7

3) 11 3/4 : 47 = 47/4 * 1/47 = 1/4 * 1/1 = 1/4

4) 1/4 + 7 = 7 1/4
