How to work it out

  1. Divide the part by the whole: 23 ÷ 78 = 0.294872
  2. Multiply by 100: 0.294872 × 100 = 29.4872%
  3. Check: Work backwards: 29.4872% of 78 is 0.294872 × 78 = 23.

Another method. As a proportion of part to whole: 23/78 = p/100, so p = 23 × 100 ÷ 78 = 29.4872%. Both methods always give the same answer.

In a spreadsheet: =23/78*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.
