Answer:
The answer is C.
Step-by-step explanation:
Think about it as substitution.
The equation given to you is 15n=10.
They are telling you that n is equal to 2/3.
So now, this is where you do the substitution.
1. Substitute 2/3 in for n.
15(2/3)=10
2. Determine if true.
15·2/3=10
3. Are they the same?
10=10
So now you know your answer is C. :)
