помогите пожалуйста ​

Answer 1

Ответ:

1/9

Пошаговое объяснение:

(6 3/4 : 4 1/2 + 2 5/7) : 8 3/7 - 2/5 = 1/10

6 3/4 : 4 1/2 = 27/4 : 9/2 = 27/4 * 2/9 = 3/2

3/2 + 2 5/7 = 3/2 + 19/7 = (21+38) / 14 = 59/14

59/14 : 8 3/7 = 59/14 : 59/7 = 59/14 * 7/59 = 1/2

1/2 - 2/5 = (5-4) / 10 = 1/10

(3 1/3 + 5 1/6) * 2/5 - 2 3/4 : 1 1/10

3 1/3 + 5 1/6 = 10/3 + 31/6 = (20+31) / 6 = 51/6 = 17/2

17/2 * 2/5 = 17/5

2 3/4 : 1 1/10 = 11/4 : 11/10 = 11/4 * 10/11 = 5/2

17/5 - 5/2 = (34-25) / 10 = 9/10

1/10 : 9/10 = 1/10 * 10/9 = 1/9
