How to work it out
- Divide the part by the whole: 200 ÷ 400 = 0.5
- Multiply by 100: 0.5 × 100 = 50%
- Check: Work backwards: 50% of 400 is 0.5 × 400 = 200.
Another method. As a proportion of part to whole: 200/400 = p/100, so p = 200 × 100 ÷ 400 = 50%. Both methods always give the same answer.
In a spreadsheet: =200/400*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
200 is exactly half of 400. The part that is left, 200, is the other 50%.
Test scores: 200 correct answers out of 400 is a score of 50%, which on a common US grading scale is an F.
Turning it around
If you know that 200 is 50% of a number, you can get that number back: 200 ÷ 0.5 = 400. And 400 as a percentage of 200 is 200%, a different answer, because the whole has changed.
