How to work it out

  1. Divide the part by the whole: 11 ÷ 80 = 0.1375
  2. Multiply by 100: 0.1375 × 100 = 13.75%
  3. Check: Work backwards: 13.75% of 80 is 0.1375 × 80 = 11.

Another method. As a proportion of part to whole: 11/80 = p/100, so p = 11 × 100 ÷ 80 = 13.75%. Both methods always give the same answer.

In a spreadsheet: =11/80*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

11 is between a tenth and a quarter of 80. The part that is left, 69, is the other 86.25%.

Test scores: 11 correct answers out of 80 is a score of 13.75%, which on a common US grading scale is an F.

Turning it around
