The percentage is calculated by dividing the part (smaller value) by the whole (larger value) and then multiplying the result by 100. The formula is:
Percentage=(PartWhole)×100\text{Percentage}=\left(\frac{\text{Part}}{\text{Whole}}\right)\times 100Percentage=(WholePart)×100
For example, if you want to find what percentage 8 is of 20, you calculate:
820×100=40%\frac{8}{20}\times 100=40%208×100=40%
This means 8 is 40% of 20
. In summary, the percentage expresses how much one quantity is of another in terms of parts per hundred.
