How to work it out

  1. Divide the part by the whole: 28 ÷ 64 = 0.4375
  2. Multiply by 100: 0.4375 × 100 = 43.75%
  3. Check: Work backwards: 43.75% of 64 is 0.4375 × 64 = 28.

Another method. As a proportion of part to whole: 28/64 = p/100, so p = 28 × 100 ÷ 64 = 43.75%. Both methods always give the same answer.

In a spreadsheet: =28/64*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.
