How to work it out

  1. Divide the part by the whole: 34 ÷ 87 = 0.390805
  2. Multiply by 100: 0.390805 × 100 = 39.0805%
  3. Check: Work backwards: 39.0805% of 87 is 0.390805 × 87 = 34.

Another method. As a proportion of part to whole: 34/87 = p/100, so p = 34 × 100 ÷ 87 = 39.0805%. Both methods always give the same answer.

In a spreadsheet: =34/87*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.
