Q. What is the result when the number

21

is decreased by

76 \%

? Round your answer to the nearest tenth.

\newline

Answer:

Calculate $76$ % of $21$ : First, we need to calculate $76\%$ of $21$ to find out how much will be decreased from the original number. $\newline$ To find $76\%$ of $21$ , we multiply $21$ by $0.76$ . $\newline$ Calculation: $21 \times 0.76$
Perform multiplication: Now, let's perform the multiplication to find the decrease amount. $\newline$ Calculation: $21 \times 0.76 = 15.96$
Subtract decrease amount: Next, we subtract the decrease amount from the original number to find the result. $\newline$ Calculation: $21 - 15.96$
Perform final subtraction: Performing the subtraction gives us the final result. $\newline$ Calculation: $21 - 15.96 = 5.04$
Round to nearest tenth: The question asks for the answer to be rounded to the nearest tenth. Rounding $5.04$ to the nearest tenth gives us $5.0$ .
