Welcome to Racket v5.3.
-> (+ 1/2 1/3)
5/6
BTW, what do the following message mean ?
(use numbers)
; loading /usr/local/lib/chicken/6/numbers.import.so ...
Note: re-importing already imported identifier: +
Note: re-importing already imported identifier: -

In racket, it is 5/6. And as i know it is 5/6 for any lisp
implementation.
Sincerely!
I suspect in Racket your above code is a syntax error. ;-)
More seriously, try this:
(use numbers)
(+ (+ 1/2 1/3))
That gives you the answer you expect.
