How to work it out

  1. Divide the part by the whole: 13 ÷ 86 = 0.151163
  2. Multiply by 100: 0.151163 × 100 = 15.1163%
  3. Check: Work backwards: 15.1163% of 86 is 0.151163 × 86 = 13.

Another method. As a proportion of part to whole: 13/86 = p/100, so p = 13 × 100 ÷ 86 = 15.1163%. Both methods always give the same answer.

In a spreadsheet: =13/86*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.
