\n" ); document.write( " $\"6%2B2%2F3=18%2F3%2B2%2F3=20%2F3\"$
\n" ); document.write( "Need a common denominator to find the difference $\"15=3%2A5\"$
\n" ); document.write( " $\"64%2F5%2A%283%2F3%29=192%2F15\"$
\n" ); document.write( " $\"20%2F3%2A%285%2F5%29=100%2F15\"$
\n" ); document.write( "The difference is then,
\n" ); document.write( " $\"D=%28192-100%29%2F15\"$
\n" ); document.write( " $\"D=92%2F15\"$
\n" ); document.write( "Three times the difference,
\n" ); document.write( " $\"3D=92%2F5\"$ \n" ); document.write( "
