Question

Вычислите:(-3 1/3):(-2,4)+7,654-(1/18+5,654)

Answer 1

(-3 1/3):(-2,4)+7,654-(1/18+5,654) = 3ц1/3

По действиям:

1). (-3 1/3):(-2,4)=3ц1/3 : 2ц4/10=3ц1/3 : 2ц2/5 = 10/3 : 12/5 = 10/3 * 5/12 = 5/3 * 5/6 = 25/18

Подставим в выражение и раскроем скобки:

25/18+7,654-1/18-5,654= (25/18 - 1/18)+(7,654-5,654)=24/18+2=4/3+2=1ц1/3+2=3ц1/3

 

Ответ: 3ц1/3

 

Answer 2

Давайте решим это уравнение по шагам.

Шаг 1: Вначале мы вычислим значение выражения (-3+1/3)/(-2,4). Для этого мы сначала выполним операцию в скобках, а затем разделим результат на -2,4.

(-3+1/3)/(-2,4) = (-9/3+1/3)/(-2,4) = (-8/3)/(-2,4)

Шаг 2: Теперь мы разделим числитель на знаменатель в этой дроби:

(-8/3)/(-2,4) = (-8/3) * (-1/2,4) = 8/3 * 1/2,4 = 8/7,2

Шаг 3: Теперь мы вычислим значение оставшихся слагаемых:

7,654-(1/18+5,654) = 7,654 - (18/18 * 1/18 + 101/18 * 9,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654) = 7,654 - (1/18 + 919,654/9,654)
