How to work it out

  1. Divide the part by the whole: 230 ÷ 400 = 0.575
  2. Multiply by 100: 0.575 × 100 = 57.5%
  3. Check: Work backwards: 57.5% of 400 is 0.575 × 400 = 230.

Another method. As a proportion of part to whole: 230/400 = p/100, so p = 230 × 100 ÷ 400 = 57.5%. Both methods always give the same answer.

In a spreadsheet: =230/400*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

230 is more than half but less than three quarters of 400. The part that is left, 170, is the other 42.5%.

Test scores: 230 correct answers out of 400 is a score of 57.5%, which on a common US grading scale is an F.

Turning it around

If you know that 230 is 57.5% of a number, you can get that number back: 230 ÷ 0.575 = 400. And 400 as a percentage of 230 is 173.913%, a different answer, because the whole has changed.
