How to work it out

  1. Divide the part by the whole: 81 ÷ 70 = 1.157143
  2. Multiply by 100: 1.157143 × 100 = 115.7143%
  3. Check: Work backwards: 115.7143% of 70 is 1.157143 × 70 = 81.

Another method. As a proportion of part to whole: 81/70 = p/100, so p = 81 × 100 ÷ 70 = 115.7143%. Both methods always give the same answer.

In a spreadsheet: =81/70*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.
