A value like 10/21, or about 47.62%, might show up when nearly half of a group chooses one option in a poll. It could also describe how much of a phone’s battery, a jar of snacks, or a school project is finished.

To picture it quickly, think of a little less than half of something. If a class has 21 students, 10 students is just one student short of half the class.
