How to work it out

  1. Divide the part by the whole: 18 ÷ 70 = 0.257143
  2. Multiply by 100: 0.257143 × 100 = 25.7143%
  3. Check: Work backwards: 25.7143% of 70 is 0.257143 × 70 = 18.

Another method. As a proportion of part to whole: 18/70 = p/100, so p = 18 × 100 ÷ 70 = 25.7143%. Both methods always give the same answer.

In a spreadsheet: =18/70*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.
