How to work it out

  1. Divide the part by the whole: 18 ÷ 77 = 0.233766
  2. Multiply by 100: 0.233766 × 100 = 23.3766%
  3. Check: Work backwards: 23.3766% of 77 is 0.233766 × 77 = 18.

Another method. As a proportion of part to whole: 18/77 = p/100, so p = 18 × 100 ÷ 77 = 23.3766%. Both methods always give the same answer.

In a spreadsheet: =18/77*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.
