How to work it out

  1. Divide the part by the whole: 42 ÷ 64 = 0.65625
  2. Multiply by 100: 0.65625 × 100 = 65.625%
  3. Check: Work backwards: 65.625% of 64 is 0.65625 × 64 = 42.

Another method. As a proportion of part to whole: 42/64 = p/100, so p = 42 × 100 ÷ 64 = 65.625%. Both methods always give the same answer.

In a spreadsheet: =42/64*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.
