How to work it out

  1. Divide the part by the whole: 15 ÷ 83 = 0.180723
  2. Multiply by 100: 0.180723 × 100 = 18.0723%
  3. Check: Work backwards: 18.0723% of 83 is 0.180723 × 83 = 15.

Another method. As a proportion of part to whole: 15/83 = p/100, so p = 15 × 100 ÷ 83 = 18.0723%. Both methods always give the same answer.

In a spreadsheet: =15/83*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.
