How to work it out

  1. Divide the part by the whole: 19 ÷ 100 = 0.19
  2. Multiply by 100: 0.19 × 100 = 19%
  3. Check: Work backwards: 19% of 100 is 0.19 × 100 = 19.

Another method. As a proportion of part to whole: 19/100 = p/100, so p = 19 × 100 ÷ 100 = 19%. Both methods always give the same answer.

In a spreadsheet: =19/100*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

19 is between a tenth and a quarter of 100. The part that is left, 81, is the other 81%.

Test scores: 19 correct answers out of 100 is a score of 19%, which on a common US grading scale is an F.

Turning it around

If you know that 19 is 19% of a number, you can get that number back: 19 ÷ 0.19 = 100. And 100 as a percentage of 19 is 526.3158%, a different answer, because the whole has changed.
