How to work it out

  1. Divide the part by the whole: 8 ÷ 90 = 0.088889
  2. Multiply by 100: 0.088889 × 100 = 8.8889%
  3. Check: Work backwards: 8.8889% of 90 is 0.088889 × 90 = 8.

Another method. As a proportion of part to whole: 8/90 = p/100, so p = 8 × 100 ÷ 90 = 8.8889%. Both methods always give the same answer.

In a spreadsheet: =8/90*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

8 is less than a tenth of 90. The part that is left, 82, is the other 91.1111%.

Test scores: 8 correct answers out of 90 is a score of 8.8889%, which on a common US grading scale is an F.

Turning it around

If you know that 8 is 8.8889% of a number, you can get that number back: 8 ÷ 0.088889 = 90. And 90 as a percentage of 8 is 1,125%, a different answer, because the whole has changed.
