Answer 1

Пошаговое объяснение:

3 1/5 : 2 2/15 = 16/5 : 32/15 = 16/5 * 15/32 = 1/1 * 3/2 = 3/2 = 1 1/2

1 7/8 : 4 1/6 = 15/8 : 25/6 = 15/8 * 6/25 = 3/4 * 3/5 = 9/20

6 1/2 : 1 6/7 = 13/2 : 13/7 = 13/2 * 7/13 = 1/2 * 7/1 = 7/2 = 3 1/2

6 2/3 : 2 7/9 = 20/3 : 25/9 = 20/3 * 9/25 = 4/1 * 3/5 = 12/5 = 2 2/5

5 3/11 : 2 7/11 = 58/11 : 29/11 = 58/11 * 11/29 = 2/1 * 1/1 = 2/1 = 2

5 1/3 : 3 5/9 = 16/3 : 32/9 = 16/3 * 9/32 = 1/1 * 3/2 = 3/2 = 1 1/2

Answer 2

Ответ:

надеюсь помогла)

Пошаговое объяснение:

1) 16/ 5 : 32/15 = 16/5 * 15/32= 3/2 = 1  1/2

вторую дробь переворачиваем, сокращаем 16 и 32, 15 и 5.

2) 15/8 : 17/6 = 15/8 * 6/17 = 45/ 68

3) 13/2 : 13/7 = 13/2 * 7/13 = 7/2 = 3,5

4) 20/3 : 25/ 9= 20/3 * 9/25= 12/5 = 2 2/5

5) 58/11 : 29/11= 58/11 * 11/29= 2

6) 16/3 : 22/9= 16/3* 9/22= 24/11 = 2 2/11
