How to work it out

  1. Divide the part by the whole: 21 ÷ 22 = 0.954545
  2. Multiply by 100: 0.954545 × 100 = 95.4545%
  3. Check: Work backwards: 95.4545% of 22 is 0.954545 × 22 = 21.

Another method. As a proportion of part to whole: 21/22 = p/100, so p = 21 × 100 ÷ 22 = 95.4545%. Both methods always give the same answer.

In a spreadsheet: =21/22*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.
