Question

-5/9+(-7 5/6) Решитее пж буду благодарна

Answer 1

-45+(12,5)=-57,5. Вроде так,но это не точно

Answer 2

Если я так поняла условие $-\frac{5}{9} +(- 7\frac{6}{6})$ то $- \frac{5}{9}- 7\frac{5}{6} = -\frac{5}{9}- \frac{47}{6} =- 8\frac{7}{18} = -\frac{151}{18}$

Answer 3

Давайте решим данное выражение: -5/9 + (-7 + 5/6).

Решение:

-5/9 + (-7 + 5/6) = -5/9 + (-42/6 + 5/6)

Сначала выполним операцию в скобках: -42/6 + 5/6 = -37/6

Теперь сложим результат с -5/9: -5/9 + (-37/6) = -5/9 - (37/6)

Для сложения дробей с разными знаменателями, нужно привести их к общему знаменателю. Общим знаменателем для 9 и 6 является 54.

-5/9 - (37/6) = -30/54 - (37/6)

Приведем -30/54 к знаменателю 6: -30/54 = -20/36 = -10/18 = -5/9

Теперь у нас есть две дроби с одинаковыми знаменателями: -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6)

Выполним вычитание: -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/9 - (37/6) = -5/
