How to work it out

  1. Divide the part by the whole: 11 ÷ 55 = 0.2
  2. Multiply by 100: 0.2 × 100 = 20%
  3. Check: Work backwards: 20% of 55 is 0.2 × 55 = 11.

Another method. As a proportion of part to whole: 11/55 = p/100, so p = 11 × 100 ÷ 55 = 20%. Both methods always give the same answer.

In a spreadsheet: =11/55*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

11 is between a tenth and a quarter of 55. The part that is left, 44, is the other 80%.

Test scores: 11 correct answers out of 55 is a score of 20%, which on a common US grading scale is an F.

Turning it around

If you know that 11 is 20% of a number, you can get that number back: 11 ÷ 0.2 = 55. And 55 as a percentage of 11 is 500%, a different answer, because the whole has changed.
