Q. What is the result when the number

90

is decreased by

75 \%

?

\newline

Answer:

Understand the problem: Understand the problem. $\newline$ We need to calculate the result of decreasing the number $90$ by $75$ %. This means we need to find $75$ % of $90$ and then subtract that value from $90$ .
Calculate $75$ % of $90$ : Calculate $75\%$ of $90$ . $\newline$ To find $75\%$ of a number, we can multiply the number by $0.75$ (since $75\%$ is the same as $\frac{75}{100}$ or $0.75$ ). $\newline$ Calculation: $90 \times 0.75 = 67.5$
Subtract values: Subtract the calculated $75\%$ from the original number. $\newline$ Now we subtract the value we found in Step $2$ from the original number $90$ . $\newline$ Calculation: $90 - 67.5 = 22.5$
