How to work it out

  1. Divide the part by the whole: 18 ÷ 47 = 0.382979
  2. Multiply by 100: 0.382979 × 100 = 38.2979%
  3. Check: Work backwards: 38.2979% of 47 is 0.382979 × 47 = 18.

Another method. As a proportion of part to whole: 18/47 = p/100, so p = 18 × 100 ÷ 47 = 38.2979%. Both methods always give the same answer.

In a spreadsheet: =18/47*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.
