Nicolas,

(a^2*c^3*d*e)/(b^2*f^3*g) + a/b
% /. a -> b*q

q + (c^3*d*e*q^2)/(f^3*g)

Hi all,
I'm afraid I couldn't find how to write the replacement rule that would
transform, for instance


a^2.c^3.d.e   a
----------- + -
b^2.f^3.g     b

into

    c^3.d.e    
q^2.-------- + q
     f^3.g     


where . is the standard Times[] and ^ is the standard Power[].

Could you please give me a hand for this ?

Many thanks in advance,

cheers,
Nicolas
