How to work it out

  1. Divide the part by the whole: 38 ÷ 78 = 0.487179
  2. Multiply by 100: 0.487179 × 100 = 48.7179%
  3. Check: Work backwards: 48.7179% of 78 is 0.487179 × 78 = 38.

Another method. As a proportion of part to whole: 38/78 = p/100, so p = 38 × 100 ÷ 78 = 48.7179%. Both methods always give the same answer.

In a spreadsheet: =38/78*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.
