How to work it out

  1. Divide the part by the whole: 81 ÷ 66 = 1.227273
  2. Multiply by 100: 1.227273 × 100 = 122.7273%
  3. Check: Work backwards: 122.7273% of 66 is 1.227273 × 66 = 81.

Another method. As a proportion of part to whole: 81/66 = p/100, so p = 81 × 100 ÷ 66 = 122.7273%. Both methods always give the same answer.

In a spreadsheet: =81/66*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.
