How to work it out

  1. Divide the part by the whole: 4 ÷ 18 = 0.222222
  2. Multiply by 100: 0.222222 × 100 = 22.2222%
  3. Check: Work backwards: 22.2222% of 18 is 0.222222 × 18 = 4.

Another method. As a proportion of part to whole: 4/18 = p/100, so p = 4 × 100 ÷ 18 = 22.2222%. Both methods always give the same answer.

In a spreadsheet: =4/18*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

4 is between a tenth and a quarter of 18. The part that is left, 14, is the other 77.7778%.

Test scores: 4 correct answers out of 18 is a score of 22.2222%, which on a common US grading scale is an F.

Turning it around

If you know that 4 is 22.2222% of a number, you can get that number back: 4 ÷ 0.222222 = 18. And 18 as a percentage of 4 is 450%, a different answer, because the whole has changed.
