The fraction 1/3 shows up whenever something is divided into three equal parts and you take one of them. For example, one-third of a pizza, a group, or an hour is about 33.33% of the whole.

To picture 1/3 quickly, imagine splitting a whole into three equal sections and shading just one section. It is a little less than half, but clearly more than one-quarter, so you can estimate it as roughly 33%.

A common mistake is thinking that 1/3 is exactly 33%, when it is slightly larger than that. The decimal continues without ending, so 33.33% is only a rounded estimate of the fraction.
