How to work it out

  1. Divide the part by the whole: 27 ÷ 54 = 0.5
  2. Multiply by 100: 0.5 × 100 = 50%
  3. Check: Work backwards: 50% of 54 is 0.5 × 54 = 27.

Another method. As a proportion of part to whole: 27/54 = p/100, so p = 27 × 100 ÷ 54 = 50%. Both methods always give the same answer.

In a spreadsheet: =27/54*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

27 is exactly half of 54. The part that is left, 27, is the other 50%.

Test scores: 27 correct answers out of 54 is a score of 50%, which on a common US grading scale is an F.

Turning it around

If you know that 27 is 50% of a number, you can get that number back: 27 ÷ 0.5 = 54. And 54 as a percentage of 27 is 200%, a different answer, because the whole has changed.
