How to work it out

  1. Divide the part by the whole: 3 ÷ 28 = 0.107143
  2. Multiply by 100: 0.107143 × 100 = 10.7143%
  3. Check: Work backwards: 10.7143% of 28 is 0.107143 × 28 = 3.

Another method. As a proportion of part to whole: 3/28 = p/100, so p = 3 × 100 ÷ 28 = 10.7143%. Both methods always give the same answer.

In a spreadsheet: =3/28*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.
