Question

(7,4+1,2):10= (2,83-1,6)*10= (25,5-3,07):100= 2,6*10+53,4:10= 8,1:100+0,28*100=

Answer 1

(7,4+1,2):10= 8,6:10= 0,86

(2,83-1,6)*10= 1,23*10= 12,3

(25,5-3,07):100= 22,43:100= 0,2243

2,6*10+53,4:10= 26+5,34= 31,34

8,1:100+0,28*100= 0,081+28= 28,081

Answer 2

Let's break down each step in the given equation:

1. (7,4 + 1,2) : 10 Calculate the sum inside the parentheses: 7.4 + 1.2 = 8.6 Now, divide 8.6 by 10: 8.6 / 10 = 0.86

2. (2.83 - 1.6) * 10 Calculate the subtraction inside the parentheses: 2.83 - 1.6 = 1.23 Now, multiply 1.23 by 10: 1.23 * 10 = 12.3

3. (25.5 - 3.07) : 100 Calculate the subtraction inside the parentheses: 25.5 - 3.07 = 22.43 Now, divide 22.43 by 100: 22.43 / 100 = 0.2243

4. 2.6 * 10 + 53.4 : 10 First, calculate 2.6 multiplied by 10: 2.6 * 10 = 26 Then, calculate 53.4 divided by 10: 53.4 / 10 = 5.34 Finally, add these results: 26 + 5.34 = 31.34

5. 8.1 : 100 + 0.28 * 100 First, calculate 8.1 divided by 100: 8.1 / 100 = 0.081 Then, calculate 0.28 multiplied by 100: 0.28 * 100 = 28 Finally, add these results: 0.081 + 28 = 28.081

So, the final results of the calculations are:

1. 0.86
2. 12.3
3. 0.2243
4. 31.34
5. 28.081
