How to work it out

  1. Divide the part by the whole: 15 ÷ 22 = 0.681818
  2. Multiply by 100: 0.681818 × 100 = 68.1818%
  3. Check: Work backwards: 68.1818% of 22 is 0.681818 × 22 = 15.

Another method. As a proportion of part to whole: 15/22 = p/100, so p = 15 × 100 ÷ 22 = 68.1818%. Both methods always give the same answer.

In a spreadsheet: =15/22*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.
