Converting integer or decimal numbers, fractions, proportions and ratios to percentages

It's very simple to write a fraction (a proportion or a ratio) or a decimal number as a percentage.

To convert a fraction:

  • - start by dividing the numerator by the denominator
  • - then multiply the result by 100%
  • By multiplying the result by 100% the value we've got at the previous step is not modified, since 100% = 100/100 = 1
  • By multiplying by 100% only the form is being changed - it's written as a percentage.

It's even simpler to write an integer or decimal number as a percentage:

  • - simply multiply the number by 100%

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%
  • 4.3 = 4.3 × 100% = (4.3 × 100)% = 430%;
