How to work it out

  1. Divide the part by the whole: 80 ÷ 8 = 10
  2. Multiply by 100: 10 × 100 = 1,000%
  3. Check: Work backwards: 1,000% of 8 is 10 × 8 = 80.

Another method. As a proportion of part to whole: 80/8 = p/100, so p = 80 × 100 ÷ 8 = 1,000%. Both methods always give the same answer.

In a spreadsheet: =80/8*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

80 is more than the whole amount (10 times as much) of 8. 80 goes past 8 by 72, which is another 900% on top of the whole.

Targets: selling 80 items against a target of 8 means reaching 1,000% of the target, beating it by 900%.

Turning it around

If you know that 80 is 1,000% of a number, you can get that number back: 80 ÷ 10 = 8. And 8 as a percentage of 80 is 10%, a different answer, because the whole has changed.
