Answer 1

Ответ:  79  59/147.

Пошаговое объяснение:

4/7•(-5 5/7)-62•(-4/3​) =

По действиям:

1) 4/7*(- 5 5/7) = - 4/7 * 40/7 = -160/49 = - 3  13/49;

2)  62*(-4/3) = - 62*4/3 =  - 248/3 = - 82  2/3;

3)  - 3  13/49  - (- 82 2/3) =  82 2/3  -  3  13/49 = 82  98/147 -3  39/147=

= 79  59/147.

4/7•(- 40/7)-62•(-4/3​) =

Answer 2

I see you've got a mathematical expression there! Let's break it down step by step.

First, we have $\frac{4}{7} \times \left(-5 \frac{5}{7}\right) - 62 \times \left(-\frac{4}{3}\right)$.

Let's simplify the terms:

1. $\frac{4}{7} \times \left(-5 \frac{5}{7}\right)$: Multiply the whole number and the fraction separately, and then subtract:

   $\frac{4}{7} \times (-5) - \frac{4}{7} \times \frac{5}{7}$

   Simplify each part:

   $-\frac{20}{7} - \frac{20}{49}$

   Combine the fractions:

   $-\frac{340}{49}$

2. $62 \times \left(-\frac{4}{3}\right)$: Multiply the whole number and the fraction:

   $62 \times \left(-\frac{4}{3}\right)$

   Simplify:

   $-\frac{248}{3}$

Now, substitute these values back into the original expression:

$-\frac{340}{49} - \frac{248}{3}$

To combine these fractions, find a common denominator, which is 147. Adjust the fractions accordingly:

$-\frac{340 \times 3}{49 \times 3} - \frac{248 \times 49}{3 \times 49}$

$-\frac{1020}{147} - \frac{12152}{147}$

Combine the numerators:

$-\frac{13172}{147}$

And simplify the fraction if possible. If you have any questions, feel free to ask!
