A value like 20% can show up in everyday life when a store offers a discount, a recipe calls for part of an ingredient, or a survey reports how many people chose an option. It’s also a handy way to describe a small share of a larger group.

To picture it quickly, imagine a group of 45 objects split into five equal groups. One of those groups is 9 objects, so 9 out of 45 is about one-fifth of the whole.

A common mix-up is thinking that 20% means 20 objects. It means 20 out of every 100, so the actual number depends on the size of the total group.
