85/100 = 85%
A value like 85/100, or 85%, shows up in everyday life as a test score, a sale discount, or a battery level. For example, scoring 85% on a quiz usually means you did well and answered most questions correctly.
You can picture 85% as 85 out of 100 shaded squares on a hundred-grid, leaving only 15 squares unshaded. It is also close to nine-tenths, so estimating it as “a little less than 90%” can help you understand its size quickly.
A common mistake is thinking that 85% means 85 points no matter what the total is. The percentage describes a portion of the whole, so 85% of 20 items is different from 85% of 100 items.
