Question

The number of eighth graders in choir is three times the number of seventh graders. If there are 48 eight graders in choir, how many seventh graders are in choir?

Answer 1

16

Explanation:

Let's say the number of 8th graders is x, and the number of 7th graders is y.

x=3y

We know that there's 48 8th graders, so

48=3y

48/3=16, so there are 16 7th graders.
