How to work it out

  1. Divide the part by the whole: 160 ÷ 400 = 0.4
  2. Multiply by 100: 0.4 × 100 = 40%
  3. Check: Work backwards: 40% of 400 is 0.4 × 400 = 160.

Another method. As a proportion of part to whole: 160/400 = p/100, so p = 160 × 100 ÷ 400 = 40%. Both methods always give the same answer.

In a spreadsheet: =160/400*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

160 is between a quarter and a half of 400. The part that is left, 240, is the other 60%.

Test scores: 160 correct answers out of 400 is a score of 40%, which on a common US grading scale is an F.

Turning it around

If you know that 160 is 40% of a number, you can get that number back: 160 ÷ 0.4 = 400. And 400 as a percentage of 160 is 250%, a different answer, because the whole has changed.
