Question

I am stuck on how to do this Algebra 1 problem

Answer 1

Hi Dylan,

 

We can solve this problem by setting up two equal ratios (also called a proportion) and then solving for our missing value (x):

    2,352 students : 90 classes = x students : 1 class

 

Since the cross products of a proportion are equal, we now have our equation to solve for x:

    (2,352)(1) = (90)(x)

    90x = 2,352

       x = 2,352 / 90

       x = 26.13

       x = 26 students per class

 

Knowing the concept of a proportion was the key to solving this problem.

 

Thanks for submitting this problem and glad to help.

 

God bless, Jordan.
