How to work it out

  1. Divide the part by the whole: 28 ÷ 57 = 0.491228
  2. Multiply by 100: 0.491228 × 100 = 49.1228%
  3. Check: Work backwards: 49.1228% of 57 is 0.491228 × 57 = 28.

Another method. As a proportion of part to whole: 28/57 = p/100, so p = 28 × 100 ÷ 57 = 49.1228%. Both methods always give the same answer.

In a spreadsheet: =28/57*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.
