How to work it out

  1. Divide the part by the whole: 18 ÷ 86 = 0.209302
  2. Multiply by 100: 0.209302 × 100 = 20.9302%
  3. Check: Work backwards: 20.9302% of 86 is 0.209302 × 86 = 18.

Another method. As a proportion of part to whole: 18/86 = p/100, so p = 18 × 100 ÷ 86 = 20.9302%. Both methods always give the same answer.

In a spreadsheet: =18/86*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.
