How to work it out

  1. Divide the part by the whole: 18 ÷ 39 = 0.461538
  2. Multiply by 100: 0.461538 × 100 = 46.1538%
  3. Check: Work backwards: 46.1538% of 39 is 0.461538 × 39 = 18.

Another method. As a proportion of part to whole: 18/39 = p/100, so p = 18 × 100 ÷ 39 = 46.1538%. Both methods always give the same answer.

In a spreadsheet: =18/39*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.
