Answer 3

Let's solve each of the calculations step by step:

1. 8,43 * 5,7: To multiply decimals, we can ignore the decimal points at first and perform the multiplication as if they were whole numbers: 8,43 * 5,7 = 843 * 57 = 48051. Now, we need to consider the decimal places in the result. The decimal point will be placed after the total number of decimal places in the original numbers: 8,43 has two decimal places, and 5,7 has one decimal place. So the final answer is 48,051.

2. 54,29 * 1000: Multiplying a number by 1000 is the same as shifting the decimal point three places to the right: 54,29 * 1000 = 54290.

3. 37,8 / 100: Dividing by 100 is equivalent to shifting the decimal point two places to the left: 37,8 / 100 = 0.378.

4. 8 / 32: Dividing 8 by 32: 8 / 32 = 0.25.

5. 3,22 / 2,8: Dividing 3,22 by 2,8: 3,22 / 2,8 ≈ 1.150.

6. 15 / 0,75: Dividing 15 by 0,75: 15 / 0,75 = 20.

So, the results of the calculations are: 8,43 * 5,7 = 48,051 54,29 * 1000 = 54,29000 (or simply 54,290) 37,8 / 100 = 0.378 8 / 32 = 0.25 3,22 / 2,8 ≈ 1.150 15 / 0,75 = 20
