A value like 21/90, or about 23.33%, might describe how many students in a class walk to school, how often a certain kind of weather occurs, or how much of a project is finished. It’s a little less than one quarter, so it can represent a noticeable but not huge share.

To picture it quickly, imagine 90 items and set aside 21 of them; about one out of every four would be close, but a bit too many. You can also think of it as roughly 23 out of every 100.

One common point of confusion is treating 23.33% as exactly one quarter. A quarter is 25%, so 21/90 is slightly smaller.
