(2,5-1 5/6)÷1 4/9-3 5/8×(-2 1/4​

Ответ:

Пошаговое объяснение:

(-2,5 - 1 5/6) : 1 4/9 - 3 5/8 * (-2 1/4) = 6

1) - 2,5 - 1 5/6 = - (25/10 + 11/6) = - (75/30 + 55/30) = - 130/30 = - 13/3

2) - 13/3 : 1 4/9 = - 13/3 : 13/9 = - 13/3 * 9/13 = - 9/3 = - 3

3) 3 5/9 * (-2 1/4) = 32/8 * (-9/4) = - 72/8 = - 9

4) - 3 - (-9) = - 3 + 9 = 6
