How to work it out

  1. Divide the part by the whole: 20 ÷ 47 = 0.425532
  2. Multiply by 100: 0.425532 × 100 = 42.5532%
  3. Check: Work backwards: 42.5532% of 47 is 0.425532 × 47 = 20.

Another method. As a proportion of part to whole: 20/47 = p/100, so p = 20 × 100 ÷ 47 = 42.5532%. Both methods always give the same answer.

In a spreadsheet: =20/47*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.
