How to work it out

  1. Divide the part by the whole: 15 ÷ 200 = 0.075
  2. Multiply by 100: 0.075 × 100 = 7.5%
  3. Check: Work backwards: 7.5% of 200 is 0.075 × 200 = 15.

Another method. As a proportion of part to whole: 15/200 = p/100, so p = 15 × 100 ÷ 200 = 7.5%. Both methods always give the same answer.

In a spreadsheet: =15/200*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

15 is less than a tenth of 200. The part that is left, 185, is the other 92.5%.

Test scores: 15 correct answers out of 200 is a score of 7.5%, which on a common US grading scale is an F.

Turning it around

If you know that 15 is 7.5% of a number, you can get that number back: 15 ÷ 0.075 = 200. And 200 as a percentage of 15 is 1,333.3333%, a different answer, because the whole has changed.
