Question

How to calculate percentage? Give example.

Answer 1

The formula for calculating the percentage:

$\mathrm{Percentage}=\frac{\mathrm{Value}}{\mathrm{Total}\mathrm{Value}}\times 100$

For example: Calculate $10\%$of $90$

$$\begin{gathered} \mathrm{P}=\frac{\mathrm{Value}}{\mathrm{Total}\mathrm{Value}}\times 100 \\ \mathrm{Value}=\frac{\mathrm{P}\times \mathrm{Total}\mathrm{Value}}{100} \\ =\frac{10\times 90}{100} \\ =9 \end{gathered}$$

Therefore, the formula for calculating is $\mathrm{Percentage}=\frac{\mathrm{Value}}{\mathrm{Total}\mathrm{Value}}\times 100$.
