Q. If

60 \%

of a number is

45

, find

20 \%

of that number.

\newline

Answer:

Convert to Decimal: Convert $60\%$ to a decimal to find the original number. $\newline$ $60\%$ as a decimal is $0.60$ . $\newline$ If $60\%$ of a number is $45$ , we can set up the equation $0.60 \times \text{number} = 45$ . $\newline$ To find the number, we divide both sides by $0.60$ . $\newline$ $\text{number} = \frac{45}{0.60}$
Calculate Original Number: Calculate the original number. $\newline$ $number = \frac{45}{0.60}$ $\newline$ $number = 75$
Convert to Decimal: Convert $20\%$ to a decimal to find $20\%$ of the original number. $\newline$ $20\%$ as a decimal is $0.20$ . $\newline$ To find $20\%$ of the number, we multiply the number by $0.20$ . $\newline$ $20\%$ of number $= 0.20 \times 75$
Calculate $20$ %: Calculate $20$ % of the number. $\newline$ $20\%$ of number $= 0.20 \times 75$ $\newline$ $20\%$ of number $= 15$
