Configuring Maxima output as an improper fraction?



Is there a way to configure Maxima to output the result as an improper
fraction?

For instance, if I enter 3/4+3/4, then it outputs 3/2.  Since I'm doing
arithmetic for a woodworking project, it would be easier if it would
output as 1+1/2.  Or 1+4/8 would be super-useful, too.  Is there a way
to make Maxima to do that?

Many thanks!

P.P.S. I'm impressed with Maxima -- after using Mathematica and Matlab,
I'm thrilled to find a mature open-source computer algebra system!  With
wxMaxima, I'll certainly be recommending it to many people!
