Question

Помогите решить уравнение
(-3 1/7)x(-8)-2,9:0,1+(11/12):(-3 2/3)

Answer 1

(-3 1/7) * (-8) - 2,9 : 0,1 + 11/12 : (-3 2/3) = - 4 3/28

1) (-3 1/7) * (-8) = (-22/7) * (-8) = 176/7 = 25 1/7
2) 2,9 : 0,1 = 29
3) 11/12 : (-3 2/3) = 11/12 : (-11/3) = 11/12 * (-3/11) = - 3/12 = - 1/4
4) 25 1/7 - 29 = - 3 6/7
5) - (3 6/7 + 1/4) = - (3 24/28 + 7/28) = - 3 31/28 = - 4 3/28
Ответ: - 4 целых 3/28.
