How to work it out

  1. Divide the part by the whole: 355 ÷ 400 = 0.8875
  2. Multiply by 100: 0.8875 × 100 = 88.75%
  3. Check: Work backwards: 88.75% of 400 is 0.8875 × 400 = 355.

Another method. As a proportion of part to whole: 355/400 = p/100, so p = 355 × 100 ÷ 400 = 88.75%. Both methods always give the same answer.

In a spreadsheet: =355/400*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.
