To find the ones that don't work, just multiply the fraction that doesn't work by the number total:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%281%2F4%29%2812%29=12%2F4=3\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So 3 songs do NOT work. This means that you need to buy 3 songs to replace the ones that do not work.
\n" ); document.write( "
\n" );
