How to work it out

  1. Divide the part by the whole: 21 ÷ 47 = 0.446809
  2. Multiply by 100: 0.446809 × 100 = 44.6809%
  3. Check: Work backwards: 44.6809% of 47 is 0.446809 × 47 = 21.

Another method. As a proportion of part to whole: 21/47 = p/100, so p = 21 × 100 ÷ 47 = 44.6809%. Both methods always give the same answer.

In a spreadsheet: =21/47*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.
