### What Does the Ratio to Percent Conversion Work?

Converting a Ratio to a Percentage: **A:B is equal to A/B*100**.
The conversion is made up of three easy steps:

- Step 2: To turn to a percentage, multiply by 100.
- Step 3: Insert the percent symbol ( percent )

For instance, if the ratio is 12:4, transform it to 12/4, which is an expression we can solve. The percentage is then calculated by multiplying the value by 100.

12 / 4 = 3

3 x100 = 300 %

To convert a ratio of 7:9 to a percentage, for example, 8:9 = 8/9*100 = 88.8 percent
