How to work it out

  1. Divide the part by the whole: 130 ÷ 400 = 0.325
  2. Multiply by 100: 0.325 × 100 = 32.5%
  3. Check: Work backwards: 32.5% of 400 is 0.325 × 400 = 130.

Another method. As a proportion of part to whole: 130/400 = p/100, so p = 130 × 100 ÷ 400 = 32.5%. Both methods always give the same answer.

In a spreadsheet: =130/400*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

130 is between a quarter and a half of 400. The part that is left, 270, is the other 67.5%.

Test scores: 130 correct answers out of 400 is a score of 32.5%, which on a common US grading scale is an F.

Turning it around

If you know that 130 is 32.5% of a number, you can get that number back: 130 ÷ 0.325 = 400. And 400 as a percentage of 130 is 307.6923%, a different answer, because the whole has changed.
