Q. What is the result when the number

22

is decreased by

2.9 \%

?

\newline

Answer:

Understand the problem: Understand the problem. $\newline$ We need to calculate the value of $22$ after it has been decreased by $2.9\%$ . This means we need to find $2.9\%$ of $22$ and then subtract that value from $22$ .
Calculate $2.9\%$ of $22$ : Calculate $2.9\%$ of $22$ . $\newline$ To find $2.9\%$ of $22$ , we convert the percentage to a decimal by dividing by $100$ and then multiply by $22$ . $\newline$ $2.9\% = \frac{2.9}{100} = 0.029$ $\newline$ $0.029 \times 22 = 0.638$
Subtract calculated value: Subtract the calculated value from the original number. $\newline$ Now we subtract the value found in Step $2$ from the original number $22$ . $\newline$ $22 - 0.638 = 21.362$
