How to work it out

  1. Divide the part by the whole: 66 ÷ 51 = 1.294118
  2. Multiply by 100: 1.294118 × 100 = 129.4118%
  3. Check: Work backwards: 129.4118% of 51 is 1.294118 × 51 = 66.

Another method. As a proportion of part to whole: 66/51 = p/100, so p = 66 × 100 ÷ 51 = 129.4118%. Both methods always give the same answer.

In a spreadsheet: =66/51*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.
