How to work it out

  1. Divide the part by the whole: 78 ÷ 78 = 1
  2. Multiply by 100: 1 × 100 = 100%
  3. Check: Work backwards: 100% of 78 is 1 × 78 = 78.

Another method. As a proportion of part to whole: 78/78 = p/100, so p = 78 × 100 ÷ 78 = 100%. Both methods always give the same answer.

In a spreadsheet: =78/78*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

78 is exactly the whole amount of 78.

Test scores: 78 correct answers out of 78 is a score of 100%, which on a common US grading scale is an A.

Turning it around

If you know that 78 is 100% of a number, you can get that number back: 78 ÷ 1 = 78. And 78 as a percentage of 78 is 100%, a different answer, because the whole has changed.
