How to work it out

  1. Divide the part by the whole: 19 ÷ 87 = 0.218391
  2. Multiply by 100: 0.218391 × 100 = 21.8391%
  3. Check: Work backwards: 21.8391% of 87 is 0.218391 × 87 = 19.

Another method. As a proportion of part to whole: 19/87 = p/100, so p = 19 × 100 ÷ 87 = 21.8391%. Both methods always give the same answer.

In a spreadsheet: =19/87*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.
