How to work it out

  1. Divide the part by the whole: 80 ÷ 31 = 2.580645
  2. Multiply by 100: 2.580645 × 100 = 258.0645%
  3. Check: Work backwards: 258.0645% of 31 is 2.580645 × 31 = 80.

Another method. As a proportion of part to whole: 80/31 = p/100, so p = 80 × 100 ÷ 31 = 258.0645%. Both methods always give the same answer.

In a spreadsheet: =80/31*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.
