Here is the explanation to which I was pointed.
http://hesweb1.med.virginia.edu/biostat/teaching/shortcourse/goldstein.ratio
s.pdf

Summary: a RHS ratio is like an interaction term so the base terms should be
included; a DV ratio  requires that the RHS vars by multiplied by the
denominator of the DV.

Comments welcome.

I was attending a workshop in which one of the presenters had a regression
in which a dependent variable was a proportion. One of the participants
noted that it was wrong but didnt follow it up with a clear explanation.

Any insights into this
