How to work it out

  1. Divide the part by the whole: 345 ÷ 400 = 0.8625
  2. Multiply by 100: 0.8625 × 100 = 86.25%
  3. Check: Work backwards: 86.25% of 400 is 0.8625 × 400 = 345.

Another method. As a proportion of part to whole: 345/400 = p/100, so p = 345 × 100 ÷ 400 = 86.25%. Both methods always give the same answer.

In a spreadsheet: =345/400*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.
