How to work it out

  1. Divide the part by the whole: 25 ÷ 400 = 0.0625
  2. Multiply by 100: 0.0625 × 100 = 6.25%
  3. Check: Work backwards: 6.25% of 400 is 0.0625 × 400 = 25.

Another method. As a proportion of part to whole: 25/400 = p/100, so p = 25 × 100 ÷ 400 = 6.25%. Both methods always give the same answer.

In a spreadsheet: =25/400*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

25 is less than a tenth of 400. The part that is left, 375, is the other 93.75%.

Test scores: 25 correct answers out of 400 is a score of 6.25%, which on a common US grading scale is an F.

Turning it around

If you know that 25 is 6.25% of a number, you can get that number back: 25 ÷ 0.0625 = 400. And 400 as a percentage of 25 is 1,600%, a different answer, because the whole has changed.
