2/5 = 40%
A fraction like 2/5, or 40%, can show up in everyday life when two out of five people choose the same snack or when a store marks an item down by that amount. It is a useful way to describe a part of a group or a change in price.
To picture 2/5 quickly, imagine five equal slices of pizza and shade in two of them. It is a little less than half, so you can estimate it as close to 50% without needing to count every time.
One common mistake is thinking 2/5 means two parts out of five uneven parts. The parts must be equal in size for the fraction to describe the whole accurately.
