A fraction like 20/30, or about 66.67%, can show up in everyday life when 20 out of 30 people choose the same option in a survey. It could also describe finishing 20 of 30 questions on an assignment or completing about two-thirds of a project.

To picture 20/30 quickly, imagine a group of 30 items divided into three equal groups of 10. Twenty items fill two of those groups, so the amount is a little more than half but not quite three-quarters.
