Q. What is the result when the number

10

is decreased by

38 \%

? Round your answer to the nearest tenth.

\newline

Answer:

Understand the problem: Understand the problem. $\newline$ We need to calculate the value of the number $10$ after it has been decreased by $38\%$ . This means we need to find $38\%$ of $10$ and then subtract that value from $10$ .
Calculate $38$ % of $10$ : Calculate $38\%$ of $10$ . $\newline$ To find $38\%$ of $10$ , we convert the percentage to a decimal by dividing by $100$ and then multiply by $10$ . $\newline$ $38\%$ as a decimal is $\frac{38}{100} = 0.38$ . $\newline$ Now, multiply $0.38$ by $10$ to find $38\%$ of $10$ . $\newline$ $10$ $2$
Decrease by calculated value: Decrease $10$ by the value found in Step $2$ . $\newline$ Now we subtract the value found from $10$ to find the decreased value. $\newline$ $10 - 3.8 = 6.2$
Round to nearest tenth: Round the answer to the nearest tenth. $\newline$ The value we found in Step $3$ is already to the nearest tenth, so no further rounding is necessary.
