Answer:
B. 30
Step-by-step explanation:
What we know: Beyunka has 6 baseballs that she keeps. That is 1/5 of the total that comes in one case.
What we need to know: How many baseballs are in one case?
What we need to do: Divide 6 by 1/5 (or multiply by 5).
6 / (1/5)
Dividing a fraction is the same thing as multiplying by its inverse.
6 * 5
Multiply 6 by 5 to get 30.
30
There are 30 baseballs in one case, so B is our answer.
