How to work it out

  1. Divide the part by the whole: 450 ÷ 500 = 0.9
  2. Multiply by 100: 0.9 × 100 = 90%
  3. Check: Work backwards: 90% of 500 is 0.9 × 500 = 450.

Another method. As a proportion of part to whole: 450/500 = p/100, so p = 450 × 100 ÷ 500 = 90%. Both methods always give the same answer.

In a spreadsheet: =450/500*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

450 is more than three quarters of 500. The part that is left, 50, is the other 10%.

Test scores: 450 correct answers out of 500 is a score of 90%, which on a common US grading scale is an A.

Turning it around

If you know that 450 is 90% of a number, you can get that number back: 450 ÷ 0.9 = 500. And 500 as a percentage of 450 is 111.1111%, a different answer, because the whole has changed.
