\r\n" );
document.write( "Tommy paints 1/9 of the fence in one hour.\r\n" );
document.write( "\r\n" );
document.write( "Huck and Tommy together paint 1 fence in one hour.\r\n" );
document.write( "\r\n" );
document.write( "Hence, Huck paints 1 - (1/9) =  (9/9)-(1/9) = 8/9 of the fence per hour.\r\n" );
document.write( "\r\n" );
document.write( "Thus, Huck can paint the fence in 9/8 hour or   hours (1 hr and 7 min 30 sec).\r\n" );
