How to Find the Percentage for a Ratio

Ratios are often expressed in the form m:n or m/n. To convert a ratio into the form of a percentage, simply divide m by n and then multiply the result by 100.

For example, If the ratio is 12:4, convert it to the form 12/4, which is an equation we can solve. After that multiply the result by 100 to get the percentage.
12 ÷ 4 = 3
3 × 100 = 300%
