How to work it out

  1. Divide the part by the whole: 57 ÷ 86 = 0.662791
  2. Multiply by 100: 0.662791 × 100 = 66.2791%
  3. Check: Work backwards: 66.2791% of 86 is 0.662791 × 86 = 57.

Another method. As a proportion of part to whole: 57/86 = p/100, so p = 57 × 100 ÷ 86 = 66.2791%. Both methods always give the same answer.

In a spreadsheet: =57/86*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.
