That's incorrect. The answer to that is still 9. The way you wrote it hides the multiplication sign making it appear as if you'd multiply the denominator by (1+3). But in actuality, you still multiply the 6 by (1+3)

It looks easier if you actually keep the multiplication sign in: 6/2*(1+2) and 6/2(1+2) are the same thing. And the answer to both is 9.
