How to work it out

  1. Divide the part by the whole: 75 ÷ 400 = 0.1875
  2. Multiply by 100: 0.1875 × 100 = 18.75%
  3. Check: Work backwards: 18.75% of 400 is 0.1875 × 400 = 75.

Another method. As a proportion of part to whole: 75/400 = p/100, so p = 75 × 100 ÷ 400 = 18.75%. Both methods always give the same answer.

In a spreadsheet: =75/400*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.

What the result means

75 is between a tenth and a quarter of 400. The part that is left, 325, is the other 81.25%.
