How to work it out

  1. Divide the part by the whole: 90 ÷ 500 = 0.18
  2. Multiply by 100: 0.18 × 100 = 18%
  3. Check: Work backwards: 18% of 500 is 0.18 × 500 = 90.

Another method. As a proportion of part to whole: 90/500 = p/100, so p = 90 × 100 ÷ 500 = 18%. Both methods always give the same answer.

In a spreadsheet: =90/500*100. Dividing the wrong way round (whole ÷ part) gives a different answer. The number after “of” is always the whole, so it goes on the bottom.

What the result means

90 is between a tenth and a quarter of 500. The part that is left, 410, is the other 82%.

Test scores: 90 correct answers out of 500 is a score of 18%, which on a common US grading scale is an F.

Turning it around

If you know that 90 is 18% of a number, you can get that number back: 90 ÷ 0.18 = 500. And 500 as a percentage of 90 is 555.5556%, a different answer, because the whole has changed.
