Question

Forty percent of the students in math class have brown eyes. If there are 10 students with brown eyes, how many students are in the class?

Answer 1

We know that there are 10 students with brown eyes, which means they represent 40% of the class. We have to find 100% of the students using the following proportion.

`\begin{gathered} (10)/(x)=(40)/(100) \\ x=(100\cdot10)/(40) \\ x=25 \end{gathered}`

Hence, there are 25 students in total.
