How to work it out

  1. Divide the part by the whole: 12 ÷ 45 = 0.266667
  2. Multiply by 100: 0.266667 × 100 = 26.6667%
  3. Check: Work backwards: 26.6667% of 45 is 0.266667 × 45 = 12.

Another method. As a proportion of part to whole: 12/45 = p/100, so p = 12 × 100 ÷ 45 = 26.6667%. Both methods always give the same answer.

In a spreadsheet: =12/45*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.
