How to calculate Percentage?
The following example problem outlines the step by step process for calculating a percentage.
- First determine the value you are trying to find the percentage of. In this example we will use 10.
- Next determine the value to divide 10 by to find the percentage. In this case, we will use 3.
- Finally, use the formula above to calculate the percentage. P = X/Y * 100 = 3/10*100 = 30%. Or in other words 3 is 30% of 100.
