To work out a percentage, use this basic formula:
Percentage=(PartWhole)×100\text{Percentage}=\left(\frac{\text{Part}}{\text{Whole}}\right)\times 100Percentage=(WholePart)×100
Steps:
- Identify the part (the portion) and the whole (the total amount).
- Divide the part by the whole to get a decimal.
- Multiply the decimal by 100 to convert it to a percentage.
For example, if you want to find what percentage 25 is of 200:
- Divide 25 by 200 = 0.125
- Multiply 0.125 by 100 = 12.5%
So, 25 is 12.5% of 200.
This method works for decimals or fractions by first converting fractions to decimals if needed and then multiplying by 100 to get the percentage.
