Question

. Вычислите: (-2,5-1 ⅚): 1⁴/⁹-3⁵/⁹×(-2¼)​

Answer 1

Ответ:

5

Пошаговое объяснение:

1) -2,5 - 1 5/6 = -2 1/2 - 1 5/6 = -2 3/6 - 1 5/6 = -3 8/6 = -4 2/6 = -4 1/3

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

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

4) -3 - (-8) = -3 + 8 = 5
