8/40 = 20%
A value like 8/40, or 20%, can show up in everyday life when a store offers a discount, a survey reports its results, or a student gets a certain share of questions right. It’s a way to describe a part of a larger group.
You can picture 20% as about one out of every five equal parts. For example, if a basket holds 40 apples, 8 apples would be about one-fifth of the basket.
A common point of confusion is thinking that 20% always means 20 items. The number of items depends on the size of the whole: 20% of 40 is 8, while 20% of 100 is 20.
