Question

10 1/7-х:1 1/7+2 5/8 =7 1/8​

Answer 1

Ответ:

(10 1/7 - y) : 1 1/7 + 2 5/8 = 7 1/8

(10 1/7 - y) : 1 1/7 = 7 1/8 - 2 5/8

(10 1/7 - y) : 1 1/7 = 6 9/8 - 2 5/8

(10 1/7 - y) : 1 1/7 = 4 4/8

10 1/7 - y = 4 1/2 * 1 1/7

10 1/7 -y = 9/2 * 8/7

10 1/7 - y = 9/2 * 4/7

10 1/7 - y = 36/7

10 1/7 -y = 5 1/7

y = 10 1/7 - 5 1/7

y = 5
