Hello,

I know this may be a simple question, but I am trying to refresh my math skills by practicing a few things, and I cannot figure out for the life of me how these two expressions are equal. Can someone please explain to me how one reduces to the other?

3 / (2*sqrt(3x)) = sqrt(3) / 2*sqrt(x)

Can I ask why and how you are able to do that?

Hi;

If you multiply the numerator of a fraction by something you must multiply the denominator by the same to have the fraction keep the same value.
