Answer 2

Ответ:

$1680$

Пошаговое объяснение:

по действиям сначала скобка

$(62 - 47) = 15$

$(12 + 18 ) = 30$

$(35 - 7) = 28$

$(16 + 24 =) = 40$

$15 \div 3 = 5$

$5 \times 30 = 150$

$150 \div 5 = 30$

$30 \times 28 = 840$

$840 \div 4 = 210$

$210 \times 40 = 8400$

$8400 \div 5 = 1680$

ну вот и все пошагово расписано

Answer 3

Let's break down the given expression step by step:

$(62 - 47) : 3 \times \left( \frac{12 + 18}{5} \right) \times \left( \frac{35 - 7}{4} \right) : \left( \frac{16 + 24}{5} \right)$

First, calculate the values inside the parentheses and brackets:

$(62 - 47) = 15$ $12 + 18 = 30$ $35 - 7 = 28$ $16 + 24 = 40$

Now, substitute these values back into the expression:

$15 : 3 \times \left( \frac{30}{5} \right) \times \left( \frac{28}{4} \right) : \left( \frac{40}{5} \right)$

Next, perform the operations inside the parentheses and brackets:

$15 : 3 \times 6 \times 7 : 8$

Now, perform the multiplications and divisions from left to right:

$15 : 18 \times 7 : 8$

$15 : 126 : 8$

Now, perform the remaining divisions:

$15 \div 126 \div 8$

$0.0178571428571429$

Therefore, the value of the given expression is approximately $0.0179$.
