How to work it out

  1. Divide the part by the whole: 10 ÷ 91 = 0.10989
  2. Multiply by 100: 0.10989 × 100 = 10.989%
  3. Check: Work backwards: 10.989% of 91 is 0.10989 × 91 = 10.

Another method. As a proportion of part to whole: 10/91 = p/100, so p = 10 × 100 ÷ 91 = 10.989%. Both methods always give the same answer.

In a spreadsheet: =10/91*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

10 is between a tenth and a quarter of 91. The part that is left, 81, is the other 89.011%.

Test scores: 10 correct answers out of 91 is a score of 10.989%, which on a common US grading scale is an F.

Turning it around

If you know that 10 is 10.989% of a number, you can get that number back: 10 ÷ 0.10989 = 91. And 91 as a percentage of 10 is 910%, a different answer, because the whole has changed.
