$\"%285%2F7%29=%28X%2F42000%29\"$
\n" ); document.write( " $\"42000%2F7=6000\"$ so if we multiply by a common 1 $\"6000%2F6000\"$
\n" ); document.write( " $\"%285%2F7%29%286000%2F6000%29=30000%2F42000\"$
\n" ); document.write( "so 30000 homes have cable so $\"42000-30000=12000\"$
\n" ); document.write( " $\"highlight%2812000%29\"$ homes dont have cable
\n" ); document.write( " \n" ); document.write( "
