How to work it out

  1. Divide the part by the whole: 12 ÷ 42 = 0.285714
  2. Multiply by 100: 0.285714 × 100 = 28.5714%
  3. Check: Work backwards: 28.5714% of 42 is 0.285714 × 42 = 12.

Another method. As a proportion of part to whole: 12/42 = p/100, so p = 12 × 100 ÷ 42 = 28.5714%. Both methods always give the same answer.

In a spreadsheet: =12/42*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.
