Question

... (-40 2/5:(-1 1/5) +2 1/3) : (-6/7)

Answer 1

Ответ:

-42

Пошаговое объяснение:

(-40 2/5:(-1 1/5) +2 1/3) : (-6/7) = -42

1)-40 2/5 : (-1 1/5) = -202/5 : (- 6/5) = -202/5 * (-5/6) = 202/6=101/3 = 33 2/3

2) 33 2/3 + 2 1/3 = 35 3/3 = 36

3) 36 : (-6/7) = 36 * (-7/6) = -42

Answer 2

To solve the expression $(-40 \frac{2}{5} : (-1 \frac{1}{5}) + 2 \frac{1}{3}) : \left(-\frac{6}{7}\right)$, follow these steps:

1. Convert Mixed Numbers to Improper Fractions:

   $-40 \frac{2}{5} = -40 - \frac{2}{5} = -40 - \frac{2}{5} = -40 - \frac{2}{5} = -\frac{202}{5}$

   $-1 \frac{1}{5} = -1 - \frac{1}{5} = -1 - \frac{1}{5} = -\frac{6}{5}$

   $2 \frac{1}{3} = 2 + \frac{1}{3} = 2 + \frac{1}{3} = \frac{7}{3}$

2. Perform Division and Addition:

   $\left(-\frac{202}{5} : \left(-\frac{6}{5}\right) + \frac{7}{3}\right)$

   First, divide $-\frac{202}{5}$ by $-\frac{6}{5}$:

   $\frac{-202}{5} \div \frac{-6}{5} = \frac{-202}{5} \times \frac{-5}{6} = \frac{202}{6} = \frac{101}{3}$

   Then add $\frac{101}{3}$ to $\frac{7}{3}$:

   $\frac{101}{3} + \frac{7}{3} = \frac{108}{3} = 36$

So, the value of the given expression is $36$.
