Решите (6 1/7- 5 3/4) : 11/14+ (3 3/4- 1 5/6) : 1/6

Verified answer

(6 1/7 - 5 3/4) : 11/14 + (3 3/4 - 1 5/6) : 1/6 = 12
1) 6 1/7 - 5 3/4 = 43/7 - 23/4 = 172/28 - 161/28 = 11/28
2) 11/28 : 11/14 = 1/2
3) 3 3/4 - 1 5/6 = 15/4 - 11/6 = 45/12 - 22/12 = 23/12
4) 23/12 : 1/6 = 23/2 = 11 1/2
5) 1/2 + 11 1/2 = 12
