How to work it out

  1. Divide the part by the whole: 17 ÷ 85 = 0.2
  2. Multiply by 100: 0.2 × 100 = 20%
  3. Check: Work backwards: 20% of 85 is 0.2 × 85 = 17.

Another method. As a proportion of part to whole: 17/85 = p/100, so p = 17 × 100 ÷ 85 = 20%. Both methods always give the same answer.

In a spreadsheet: =17/85*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

17 is between a tenth and a quarter of 85. The part that is left, 68, is the other 80%.

Test scores: 17 correct answers out of 85 is a score of 20%, which on a common US grading scale is an F.

Turning it around

If you know that 17 is 20% of a number, you can get that number back: 17 ÷ 0.2 = 85. And 85 as a percentage of 17 is 500%, a different answer, because the whole has changed.
