A value of one-third shows up in everyday situations, like splitting a pizza evenly among three people or dividing an hour into three equal parts. Each person gets about 33.33% of the pizza, and each part of the hour lasts 20 minutes.

To picture one-third quickly, imagine a shape divided into three equal sections and shade one of them. It’s a little less than half, but more than a quarter.

One common point of confusion is treating 33.33% as perfectly exact. It’s a rounded way to describe one-third, so using it three times gives 99.99% rather than exactly 100%.
