How to work it out

  1. Divide the part by the whole: 18 ÷ 28 = 0.642857
  2. Multiply by 100: 0.642857 × 100 = 64.2857%
  3. Check: Work backwards: 64.2857% of 28 is 0.642857 × 28 = 18.

Another method. As a proportion of part to whole: 18/28 = p/100, so p = 18 × 100 ÷ 28 = 64.2857%. Both methods always give the same answer.

In a spreadsheet: =18/28*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.
