If you change everything to a common denominator, it's much easier. Let's use 20ths.
\n" ); document.write( " $\"1%2F4\"$ = $\"5%2F20\"$
\n" ); document.write( " $\"1%2F10\"$ = $\"2%2F20\"$
\n" ); document.write( " $\"3%2F4\"$ = $\"15%2F20\"$
\n" ); document.write( " $\"9%2F10\"$ = $\"18%2F20\"$
Now your problem is $\"5%2F20\"$ - $\"2%2F20\"$ over $\"15%2F20\"$ - $\"18%2F20\"$ , or
\n" ); document.write( " $\"3%2F20\"$ over $\"-3%2F20\"$
\n" ); document.write( "Cancel out the 20ths to get
\n" ); document.write( " $\"3%2F-3\"$ which reduces to -1 \n" ); document.write( "

\n" );
