484/605 = 80%
A value like 484/605, or 80%, can show up in everyday situations such as getting 80% of questions correct on a test. It could also describe a store sale, a battery level, or the share of students who finished an assignment.
You can picture 80% as about four out of every five items. It is close to a full amount, but leaving out roughly one-fifth helps you estimate it quickly.
A common mistake is to think 80% means 80 items, even when the total is not 100. The percentage describes a portion of the whole, so the actual number represented depends on the total amount.
