What is the equation for the mechanical advantage of a lever?

MA = length of effort arm / length of resistance arm

MA = length of resistance arm/length of the effort arm

MA = length of effort arm + length of resistance arm

MA = length of effort arm * length of resistance arm

I think it is the second one, is that correct? HELP!
