How to work it out

  1. Divide the part by the whole: 18 ÷ 79 = 0.227848
  2. Multiply by 100: 0.227848 × 100 = 22.7848%
  3. Check: Work backwards: 22.7848% of 79 is 0.227848 × 79 = 18.

Another method. As a proportion of part to whole: 18/79 = p/100, so p = 18 × 100 ÷ 79 = 22.7848%. Both methods always give the same answer.

In a spreadsheet: =18/79*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.
