Answer 2

Ответ:

Пошаговое объяснение:

1)

7/24 * 16 = 7/3 * 2 = 14/3 = 4. 2/3

2)

2. 1/4 * 16/27 * 4. 1/3 =

9/4 * 16/27 * 13/3 =

1/1 * 4/3 * 13/3 = 4/3 * 13/3 = 52/9 =

5. 7/9

3)

57 * 6/19 = 3 * 6/1 = 18/1 = 18

4)

0,6 * 1. 2/3 = 6/10 * 5/3 = 30/30 = 1

5)

7/18 * 90/77 = 1/1 * 5/11 = 5/11

6)

32/45 * 1,25 = 32/45 * 1. 25/1 00 =

32/45 * 1. 1/4 = 32/45 * 5/4 = 8/9 * 1/1 = 8/9

7)

19/1 00 * 5/38 = 1/20 * 1/2 = 1/40

8)

(3/7)³ = 3/7 * 3/7 * 3/7 = 27/343

9)

3. 5/9 * 5. 1/4 = 32/9 * 21/4 = 8/3 * 7/1 = 56/3 = 18. 2/3

10)

(3. 1/4)² = (13/4)² = 13/4 * 13/4 = 169/16 = 10. 9/16
