How to work it out

  1. Divide the part by the whole: 28 ÷ 18 = 1.555556
  2. Multiply by 100: 1.555556 × 100 = 155.5556%
  3. Check: Work backwards: 155.5556% of 18 is 1.555556 × 18 = 28.

Another method. As a proportion of part to whole: 28/18 = p/100, so p = 28 × 100 ÷ 18 = 155.5556%. Both methods always give the same answer.

In a spreadsheet: =28/18*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.
