document.write( "The first man can do a job in 5 hours, \r\n" );
document.write( "so in 1 hour he can do 1/5th of the job.\r\n" );
document.write( "\r\n" );
document.write( "The second man can do a job in 6 hours, \r\n" );
document.write( "so in 1 hour he can do 1/6th of the job.\r\n" );
document.write( "\r\n" );
document.write( "The third man can do a job in 7 hours, \r\n" );
document.write( "so in 1 hour he can do 1/7th of the job.\r\n" );
document.write( "\r\n" );
document.write( "So add the fractions 1/5 + 1/6 + 1/7 = ???\r\n" );
