How to work it out

  1. Divide the part by the whole: 54 ÷ 80 = 0.675
  2. Multiply by 100: 0.675 × 100 = 67.5%
  3. Check: Work backwards: 67.5% of 80 is 0.675 × 80 = 54.

Another method. As a proportion of part to whole: 54/80 = p/100, so p = 54 × 100 ÷ 80 = 67.5%. Both methods always give the same answer.

In a spreadsheet: =54/80*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

54 is more than half but less than three quarters of 80. The part that is left, 26, is the other 32.5%.

Test scores: 54 correct answers out of 80 is a score of 67.5%, which on a common US grading scale is a D.
