Answer 2

Ответ:

1) (1213/17 + 34/17)= 1247/17

2) (53/5 -24/5)= 29/5

3)40:1247/17= 40*17/1247=680/1247

4)29/5:7=29/5*1/7=29/35

5)680/1247+29/35=(23800+36163)/43645=59963/43645=1 16318/43645

Answer 3

To solve the given expression, let's break it down step by step:

First, simplify the terms inside the parentheses: 1213/17 + 34/17 = (1213 + 34) / 17 = 1247 / 17

Next, simplify the terms outside the parentheses: 53/5 - 24/5 = (53 - 24) / 5 = 29 / 5

Now, substitute the simplified values back into the original expression: 40: (1247/17 + 29/5) : 7

Now, simplify the addition inside the first set of parentheses: 1247/17 + 29/5 = (1247 * 5 + 17 * 29) / (17 * 5) = (6235 + 493) / 85 = 6728 / 85

Substitute the value back into the expression: 40: (6728/85) : 7

Now, divide 6728/85: 6728 / 85 = 79.15294117647059

Finally, substitute the result back into the expression: 40: 79.15294117647059 : 7

Now, divide 79.15294117647059 by 7: 79.15294117647059 / 7 = 11.307563025210083

Therefore, the final answer is approximately 11.3076.
