#(9q)/q# (#q!=0# for #qin ZZ#)

Explanation:

A rational number is one of the form: #p/q# (#q!=0# for #{p,q}in ZZ#)

In the sense that #9=9/1#, 9 is already a rational number.

However, in general, we can set #9=p/q -> p=9q#

Hence any #(9q)/q# (#q!=0# for #qin ZZ#) form rational numbers that equal 9.
