I have a problem with calculating a fraction, the reason is that both the
nominator and denominator are variables.
So I am looking for some way to make this linear:
x_suj = p_s * (y_suj/w_su) or well just find what this fraction is:
where p_s is a constant, x,y and w are integer variables. and I also need
to avoid the division with 0 problem.

A lot of things can be linearized over a small enough region.
That said, if you have division by zero issues,
you probably need to reformulate.
