  <p>My question is how do I solve this compiling issue on lines 7 &amp; 11? This class takes the numerators and denominators entered in the main method class not shown here and simplifies the rational number with the GCD. Also, when I do put in a return type it just comes up with even more errors and warnings so I'm stumped! Thank you for looking and all of your inputs.</p>
