Question

The eight grade class received surveys regarding Internet access in their homes. Three-fourths of the eight grade class has access to the Internet in their homes. If 120 students have access to the Internet, how many students are in the eighth grade class? Explain.

Answer 1

\[\frac{3}{4}x=120\]
Times each side by the inverse which is 4/3.
\[x=120\frac{4}{3}\]
\[x=160\]

Answer 2

Since there are 120 who have internet access and that represents 3/4 of the class. We list the whole class as x and solve based on that presumption.
