Comment (by iorate <iorate_stage@…>):

 The solution doesn't work with ratio<0, 2> and so on, I think.
 The following is better:
 {{{
 template <class R, boost::intmax_t D> struct ratio_add<R, ratio<0, D> > {

     typedef R type;

 };

 template <class R, boost::intmax_t D> struct ratio_subtract<R, ratio<0, D>
 > {

     typedef R type;

 };
 }}}
