Answer:

C

Step-by-step explanation:

Okay, first you would add up all the gumballs.

2+3+2=7

Now that will be the denominator.

Now for the numerator. You will check the question and find how man green gumballs there are. There are 3. So, now make it a fraction.

[tex]\frac{3}{7}[/tex]

The answer choice is C.

Hope this helped!
