How to work it out

  1. Divide the part by the whole: 11 ÷ 28 = 0.392857
  2. Multiply by 100: 0.392857 × 100 = 39.2857%
  3. Check: Work backwards: 39.2857% of 28 is 0.392857 × 28 = 11.

Another method. As a proportion of part to whole: 11/28 = p/100, so p = 11 × 100 ÷ 28 = 39.2857%. Both methods always give the same answer.

In a spreadsheet: =11/28*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.
