Q. What is the result when the number

12

is decreased by

25 \%

?

\newline

Answer:

Understand the problem: Understand the problem. $\newline$ We need to calculate the value of the number $12$ after it has been decreased by $25$ %. This means we need to find $75$ % of $12$ , since decreasing a number by $25$ % is the same as keeping $75$ % of it.
Calculate $25$ % of $12$ : Calculate $25\%$ of $12$ . $\newline$ To find $25\%$ of $12$ , we can multiply $12$ by $0.25$ (since $25\%$ is the same as $0.25$ in decimal form). $\newline$ $25\%$ of $12$ = $12$ $0$
Subtract values to find result: Subtract the $25\%$ value from the original number. $\newline$ Now we subtract the value we found in Step $2$ from the original number $12$ to find the decreased value. $\newline$ $12 - 3 = 9$
