How to work it out

  1. Divide the part by the whole: 13 ÷ 57 = 0.22807
  2. Multiply by 100: 0.22807 × 100 = 22.807%
  3. Check: Work backwards: 22.807% of 57 is 0.22807 × 57 = 13.

Another method. As a proportion of part to whole: 13/57 = p/100, so p = 13 × 100 ÷ 57 = 22.807%. Both methods always give the same answer.

In a spreadsheet: =13/57*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.
