How to work it out

  1. Divide the part by the whole: 52 ÷ 81 = 0.641975
  2. Multiply by 100: 0.641975 × 100 = 64.1975%
  3. Check: Work backwards: 64.1975% of 81 is 0.641975 × 81 = 52.

Another method. As a proportion of part to whole: 52/81 = p/100, so p = 52 × 100 ÷ 81 = 64.1975%. Both methods always give the same answer.

In a spreadsheet: =52/81*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.
