Answer 1

Ответ:

Пошаговое объяснение:

1) 71,33 - 16,8: (8,08 + 1,12) =  $-69 \frac{1159}{2300}$

1a/    (8,08 + 1,12=9.2

1b/    16,8 : 9.2 = $= \frac{168}{92} = \frac{42}{23}$

1c/    71.33  $- \frac{42}{23}$   = $-69 \frac{1159}{2300}$

2) (0,62 * 0,56 – 0,29)* (8,44 - 5,34);

2a/    (0,62 * 0,56 – 0,29) = 0.0572

2b/      (8,44 - 5,34) = 3.1

2c/      0.0572 * 3.1 = 0.17732

9) 62,9 + (12,5 – 7,6 + 3,21):0,1; = = 143,2

12,5 – 7,6 + 3,21 = 8.11

8.11 : 0.1 = 81.1

62.9 + 81.1 = 143,2

4) (8,25 -0,1 - 0,025) · (2,21 + 4,79) : 0,1. =  568,75

(8,25 -0,1 - 0,025 ) = 8,125

2.21 + 4.79 = 7

8.125 *7 = 56.875

56.875 : 0.1 = 568.75

Answer 2

It seems like you've provided a series of mathematical expressions, and you would like me to calculate the results. Let's break it down step by step:

1. 71.33 - 16.8 / (8.08 + 1.12) First, calculate the denominator: 8.08 + 1.12 = 9.2 Then, divide 16.8 by 9.2: 16.8 / 9.2 ≈ 1.8261 (rounded to 4 decimal places) Finally, subtract this result from 71.33: 71.33 - 1.8261 ≈ 69.5039 (rounded to 4 decimal places)

2. (0.62 * 0.56 - 0.29) * (8.44 - 5.34) First, calculate the value inside the first set of parentheses: 0.62 * 0.56 - 0.29 ≈ 0.3472 (rounded to 4 decimal places) Then, calculate the value inside the second set of parentheses: 8.44 - 5.34 = 3.1 Finally, multiply the two results: 0.3472 * 3.1 ≈ 1.07612 (rounded to 5 decimal places)

3. 62.9 + (12.5 - 7.6 + 3.21) / 0.1 First, calculate the value inside the parentheses: 12.5 - 7.6 + 3.21 = 8.11 Then, divide 8.11 by 0.1: 8.11 / 0.1 = 81.1 Finally, add this result to 62.9: 62.9 + 81.1 = 144

4. (8.25 - 0.1 - 0.025) * (2.21 + 4.79) / 0.1 First, calculate the value inside the first set of parentheses: 8.25 - 0.1 - 0.025 = 8.125 Then, calculate the value inside the second set of parentheses: 2.21 + 4.79 = 7 Finally, divide the two results by 0.1: 8.125 * 7 / 0.1 = 568.75

So, the results are as follows:

1. 69.5039
2. 1.07612
3. 144
4. 568.75
