The fraction 2/3, or about 66.67%, shows up in everyday situations such as finishing two out of three tasks or having two-thirds of a pizza left. You might also hear it when comparing survey results, attendance, or the amount of a recipe you have prepared.

To picture 2/3 quickly, imagine a whole divided into three equal parts and shade two of them. It is a little more than half, but not as much as three-quarters, so estimating it as around 67% is usually useful.

A common mistake is treating 2/3 as exactly 66% or exactly 67%, even though both are only rounded versions. Another point of confusion is forgetting that the three parts must be equal in size for the fraction to represent 2/3.
