What? It's usually 0.

x/10=2/39 x=?

This problem uses a reciprocal to make the x/10=x which equals 1. You then Multiply the 10/x by 2/39 for the answer.

I'm sorry? X=2/39*10=2/3.9=0.512820 recurring.

Huh? For that to work, x must be 0. If you, say, put x being 5, then it'd be 5/10=5, which is impossible.
Oh! I think you mean x/10*x=1.That's the reciprocal.

EDIT: Whoops. No, 1/x*x=1 is the reciprocal. I have no idea what you were doing there.
