Please help me with this Algebra I problem. I am supposed to come up with an answer of r/g. But I keep getting 3 r/g. I am trying to figure out what the formula is to come to this answer:

36 x 2rh
___________
3 x (9hg)

Thanks!

$\frac{36\times 2\times rh}{3 \times 9\times hg}=\frac{4\times9\times 2\times rh}{3\times 9\times hg}=\frac{8r}{3g}$
