<p>how do you multiply them if neither number can go into each other when cross reducing, would you just keep the same number?</p>
This could have been cross cancelled two more times. The 9 &amp; 3 (either denominator!) could be cross cancelled so you would have either 3/1 x 7/3 = 1/1 x 7/1 = 7 OR 3/3 x 7/1 = 1 x 7 = 7. I review this with 6th graders by writing a ridiculously long multiplication problem to demonstrate how much you can simplify a problem.
