How to work it out

  1. Divide the part by the whole: 12 ÷ 70 = 0.171429
  2. Multiply by 100: 0.171429 × 100 = 17.1429%
  3. Check: Work backwards: 17.1429% of 70 is 0.171429 × 70 = 12.

Another method. As a proportion of part to whole: 12/70 = p/100, so p = 12 × 100 ÷ 70 = 17.1429%. Both methods always give the same answer.

In a spreadsheet: =12/70*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.
