How to work it out

  1. Divide the part by the whole: 50 ÷ 400 = 0.125
  2. Multiply by 100: 0.125 × 100 = 12.5%
  3. Check: Work backwards: 12.5% of 400 is 0.125 × 400 = 50.

Another method. As a proportion of part to whole: 50/400 = p/100, so p = 50 × 100 ÷ 400 = 12.5%. Both methods always give the same answer.

In a spreadsheet: =50/400*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

50 is between a tenth and a quarter of 400. The part that is left, 350, is the other 87.5%.

Test scores: 50 correct answers out of 400 is a score of 12.5%, which on a common US grading scale is an F.

Turning it around

If you know that 50 is 12.5% of a number, you can get that number back: 50 ÷ 0.125 = 400. And 400 as a percentage of 50 is 800%, a different answer, because the whole has changed.
