16/20 = 80%
A value like 16/20, or 80%, can show up in everyday life when you score 16 correct answers out of 20 on a quiz. It can also describe finishing 16 of 20 tasks, attending 16 of 20 practices, or having 16 out of 20 items ready.
You can picture 16/20 as four-fifths of a whole, with most of it filled and only one-fifth left over. As a quick estimate, think of it as about 8 out of every 10 parts, which is clearly more than half but not quite complete.
A common mistake is treating 80% as if it means 80 points or 80 items, no matter what the total is. The percentage describes a portion of the whole, so 80% of 20 is different from 80% of 100.
