Converting Fractions to Percent

To convert a fraction into a percent, divide the numerator by the denominator, then multiply the result by 100. For instance, to convert the fraction $\frac{1}{2}$ into a percent, divide 1 by 2 to get 0.5, then multiply by 100 to get 50%.

Important Notes

The word 'percent' means 'per 100'. So, when you convert a fraction to a percent, you're essentially expressing the fraction as a number out of 100.
The numerator of a fraction is the number on top, and the denominator is the number on the bottom.
Simplifying your fractions before converting them to percentages is helpful but not required.
When converting decimals to percentages, round to two decimal places unless otherwise indicated.

Mathematical Notation

$\frac{a}{b}$ represents a fraction where 'a' is the numerator and 'b' is the denominator.

$a \times 100$ represents multiplication of 'a' by 100.

Remember to use the correct notations when solving problems.

Why It Works

This method works because dividing the numerator by the denominator gives you a decimal that represents the fraction. Multiplying this decimal by 100 then gives you the equivalent percentage.

Remember

To convert a fraction to a percent, divide the numerator by the denominator and multiply the result by 100.
