How to work it out

  1. Divide the part by the whole: 81 ÷ 28 = 2.892857
  2. Multiply by 100: 2.892857 × 100 = 289.2857%
  3. Check: Work backwards: 289.2857% of 28 is 2.892857 × 28 = 81.

Another method. As a proportion of part to whole: 81/28 = p/100, so p = 81 × 100 ÷ 28 = 289.2857%. Both methods always give the same answer.

In a spreadsheet: =81/28*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.
