 63                                       3(23)
----- could be re-written as --------------
 35                                        5(7)

None of these factors {3, 23, 5, 7} is further factorable, and none cancel.

Thus, 63/35 has already been expressed in lowest terms.

You could rewrite 63/35 as a mixed number:  1 28/35
