The fraction 2/5, or 40%, can show up in everyday situations such as a sale, a test score, or a classroom survey. For example, if 2 out of every 5 students prefer a certain activity, that group represents 40% of the class.

To picture 2/5 quickly, imagine a whole divided into 5 equal parts and shade 2 of them. It is a little less than half, so estimating it as “about two-fifths” or “slightly under 50%” can help.

A common mistake is thinking that 2/5 is close to 2%, because both numbers include a 2. The denominator matters: 2/5 describes 2 parts out of 5 equal parts, not 2 parts out of 100.
