Sagot :

To find 10% of a number, follow these steps:

1. Understand the percentage: 10% means 10 out of 100. In other words, you want to find what part 10 out of 100 is of the whole number.

2. Convert the percentage to a decimal: Percentages are simply fractions out of 100. Therefore, 10% can be converted to a decimal by dividing by 100. So, 10% becomes 0.10.

3. Multiply the decimal by the number: We need to multiply the decimal form (0.10) by the number in question, which is 40.

So, calculate:
[tex]\[ 0.10 \times 40 \][/tex]

4. Perform the multiplication: Carry out the multiplication to get the final answer.

Thus, [tex]\( 0.10 \times 40 = 4.0 \)[/tex].

Therefore, 10% of 40 is 4.0.
