What i do not understand is why do you multiply each side by 2? Is it because that is the denominator? Also, when you do this it comes out to 2D/R=1G, so because its 1G then its just G correct? So the answer is 2D/R=G?

Now lets say the problem was different.

D=3/4GR Would it be

(4)D=4(3/4)GR

4D=3G (move the r to the other side)

4D/R=3G Would that be correct? Im new to this stuff so just trying to understand how it works, would that 3 be correct beside the G? Doesn`t seem right.
