document.write( "John makes \"1%2F30\" of the job per minute.\r\n" );
document.write( "\r\n" );
document.write( "Jack makes \"1%2F20\" of the job per minute.\r\n" );
document.write( "\r\n" );
document.write( "Working together they make \"1%2F20+%2B+1%2F30\" = \"3%2F60+%2B+2%2F60\" = \"5%2F60\" = \"1%2F12\" of the job per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, it will require 12 minutes for both to complete the job working together.\r\n" );
