The fraction 79/80 converts to 98.75% when expressed as a percentage. This shows that the value is very close to a full 100%, just a tiny bit less.
When you think of 79 out of 80 parts, imagine a pizza cut into 80 slices and you eat 79 of them. You’re missing only one slice, which is why the percentage is so high.
In everyday terms, a score of 98.75% means almost perfect performance. It’s the kind of result you’d see on a test where only one question was answered incorrectly out of many.
Because the fraction is so near to 1, its percentage is also near to 100%. This makes 79/80 a useful example when you want to show a value that’s just shy of the whole.
