Q. What is the result when the number

80

is increased by

10 \%

?

\newline

Answer:

Understand and Determine: Understand the problem and determine what is being asked. $\newline$ We need to calculate the result of increasing the number $80$ by $10$ %. To do this, we will calculate $10$ % of $80$ and then add this value to $80$ .
Calculate $10$ % of $80$ : Calculate $10$ % of $80$ . $\newline$ To find $10$ % of a number, we can multiply the number by $0.10$ (which is the decimal equivalent of $10$ %). $\newline$ So, $10$ % of $80$ is $80 \times 0.10$ .
Perform Calculation: Perform the calculation from Step $2$ . $\newline$ $80 \times 0.10 = 8$ $\newline$ So, $10\%$ of $80$ is $8$ .
Add to Original Number: Add the $10\%$ calculated to the original number. $\newline$ Now we add the $10\%$ (which is $8$ ) to the original number (which is $80$ ). $\newline$ $80 + 8 = 88$
Verify Result: Verify the result. $\newline$ To check our work, we can consider if adding $10\%$ to a number should result in a number that is larger than the original. Since $88$ is greater than $80$ , our calculation seems correct.
