How to work it out

  1. Divide the part by the whole: 10 ÷ 18 = 0.555556
  2. Multiply by 100: 0.555556 × 100 = 55.5556%
  3. Check: Work backwards: 55.5556% of 18 is 0.555556 × 18 = 10.

Another method. As a proportion of part to whole: 10/18 = p/100, so p = 10 × 100 ÷ 18 = 55.5556%. Both methods always give the same answer.

In a spreadsheet: =10/18*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

10 is more than half but less than three quarters of 18. The part that is left, 8, is the other 44.4444%.

Test scores: 10 correct answers out of 18 is a score of 55.5556%, which on a common US grading scale is an F.

Turning it around

If you know that 10 is 55.5556% of a number, you can get that number back: 10 ÷ 0.555556 = 18. And 18 as a percentage of 10 is 180%, a different answer, because the whole has changed.
