How to work it out

  1. Divide the part by the whole: 18 ÷ 25 = 0.72
  2. Multiply by 100: 0.72 × 100 = 72%
  3. Check: Work backwards: 72% of 25 is 0.72 × 25 = 18.

Another method. As a proportion of part to whole: 18/25 = p/100, so p = 18 × 100 ÷ 25 = 72%. Both methods always give the same answer.

In a spreadsheet: =18/25*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

18 is more than half but less than three quarters of 25. The part that is left, 7, is the other 28%.

Test scores: 18 correct answers out of 25 is a score of 72%, which on a common US grading scale is a C.

Turning it around

If you know that 18 is 72% of a number, you can get that number back: 18 ÷ 0.72 = 25. And 25 as a percentage of 18 is 138.8889%, a different answer, because the whole has changed.
