Question

8,5 + 2,7 + 6,3 = 10 ⋅ 0,05 ⋅ 5 = (38,6 + 105) – 18,6 = 2,1 ⋅ (3,7 + 6,3) = 1,72 ⋅ 63 = 8,142 − 5,387 = 73,94 + 93,1 = 250,6 : 7 =

Answer 1

Ответ:

8,5 + 2,7 + 6,3 = 17,5

10 ⋅ 0,05 ⋅ 5 = 2,5

(38,6 + 105) – 18,6 = 125

2,1 ⋅ (3,7 + 6,3) = 21

1,72 ⋅ 63 = 108,36

8,142 − 5,387 = 2755

73,94 + 93,1 = 167,04

250,6 : 7 =35,8

Answer 2

Let's calculate the expressions step by step:

1. 8.5 + 2.7 + 6.3 = 17.5
2. 10 * 0.05 * 5 = 2.5
3. (38.6 + 105) - 18.6 = 125 - 18.6 = 106.4
4. 2.1 * (3.7 + 6.3) = 2.1 * 10 = 21
5. 1.72 * 63 = 108.36
6. 8.142 - 5.387 = 2.755
7. 73.94 + 93.1 = 167.04
8. 250.6 / 7 ≈ 35.8 (rounded to one decimal place)

So, the result of the expressions is as follows:

1. 17.5
2. 2.5
3. 106.4
4. 21
5. 108.36
6. 2.755
7. 167.04
8. 35.8
