Variable name that is a ratio

Hi all,

I want to have variables as follows: T/W=0.8 or W/S=100 etc. However Mathcad  won't let me define a variable like that, because I think it actually divide or sth. Is there a way around this?

I don't need to know the W or T, I just want to use T/W or W/S ratio in subsequent calculations.

As an example if I want to solve for V=sqrt(2(W/S)/rho*sigma*CL), I would just use the W/S ratio that I would have already defined.
