find the ratio

Question

In a class of 26 people, 7 received an A. If the same ratio of students received an A in a class of 442, how many students would you expect to receive an A? Explain solution.

Answer 1

 

The ratio of A's to total is:

 

   

    7           X

------- = --------

  26          442

 

Cross Multiply:  7 * 442 = 26 x 

 

                        7*442/26 = x

 

                       x = 119
