Question

# What percentage of 64 is 8?

$\dfrac{x}{100}\times 64=8$
$x=\dfrac{8\times 100}{64}$
$\Rightarrow x=\dfrac{100}{8}=\dfrac{25}{2}=12.5\%$
Note: If you face a problem in interpreting the percentage related problems, you can remember a small trick, to convert the statement $x\%\text{ of y units}$ , replace the % sign $\dfrac{1}{100}$ , ‘of’ by a multiplication sign and the unit of you answer is ‘units’. So, the mathematical representation is $\left( \dfrac{x}{100}\times y \right)units$ .
