How to work it out

  1. Divide the part by the whole: 150 ÷ 400 = 0.375
  2. Multiply by 100: 0.375 × 100 = 37.5%
  3. Check: Work backwards: 37.5% of 400 is 0.375 × 400 = 150.

Another method. As a proportion of part to whole: 150/400 = p/100, so p = 150 × 100 ÷ 400 = 37.5%. Both methods always give the same answer.

In a spreadsheet: =150/400*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

150 is between a quarter and a half of 400. The part that is left, 250, is the other 62.5%.

Test scores: 150 correct answers out of 400 is a score of 37.5%, which on a common US grading scale is an F.

Turning it around

If you know that 150 is 37.5% of a number, you can get that number back: 150 ÷ 0.375 = 400. And 400 as a percentage of 150 is 266.6667%, a different answer, because the whole has changed.
