Percentages are another way of showing a fraction. They treat the whole thing as being made of 100 parts.

To convert to a fraction you use this 100 as the denominator and the actual percentage as the numerator.

You then simplify the fraction if possible.

Example

75% = ⁷⁵/₁₀₀.

Simplify: The highest common factor of 75 and 100 is 5. Divide both the numerator and the denominator by 5.

75% = ³/₄.
