36 students have traveled outside of the United States, when there are total 120 sixth graders.

<u><em>Explanation</em></u>

The number of students traveled outside of the United States is 9 when there is total 30 sixth graders. So, the ratio of the student traveled to the total students will be 9: 30 = 3: 10

Now there are total of 120 sixth graders in the school and lets assume the number of students traveled outside the United states is x . That means the ratio...

x: 120 = 3:10 \\ \\ \frac{x}{120}=\frac{3}{10}  \\ \\ 10x=360\\ \\ x=\frac{360}{10} \\ \\ x= 36

So, 36 students have traveled outside of the United States.
