## Transforming fractions, proportions and ratios to percentages

It's very simple to transform a fraction, a proportion or a ratio to a percentage. Start by dividing the numerator by the denominator and then multiply the result by 100%. By multiplying the result by 100% the value obtained at the previous step is not modified, since 100% = 100/100 = 1. By multiplying by 100% only the form is being modified, into a percentage.

#### Examples

- 1/4 = 0.25 = 0.25 * 100% = (0.25 * 100)% = 25%
- 7/8 = 0.875 = 0.875 * 100% = (0.875 * 100)% = 87.5%
- 1.3/9.4 ~= 0.138297 = 0.138297 * 100% = (0.138297 * 100)% = 13.8297%
