Question

Помогите решить:
17 + 10 : (14 6/25 - 11 37/50 - 10)

Answer 1

17 + 10 : (14 6/25 - 11 37/50 - 10) = 15 2/3,

1) 14 6/25 - 11 37/50 = (14 - 11) + (6/25 - 37/50) = 3 + (12/50 - 37/50) = 3 -      25/50 = 3 - 1/2 = 2 1/2,
2) 2 1/2 - 10 = -7 1/2,
3) 10 : (-7 1/2) = - 10 : 15/2 = -10 * 2/15 = -4/3 = -1 1/3,
4)17 + (-1 1/3) = 17 - 1 1/3 = 15 2/3
