\"5%2F9\"+\"7%2F9\"
\n" ); document.write( "=\"12%2F9\"
\n" ); document.write( "=1 \"3%2F9\"
\n" ); document.write( "=1 \"1%2F3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are 60 minutes in an hour. Since we want to know what \"1%2F3\" of an hour is, divide 60 by 3:
\n" ); document.write( "\"%2860%29%281%2F3%29\"
\n" ); document.write( "=20 min\r
\n" ); document.write( "\n" ); document.write( "1 \"1%2F3\"= hour and 20 min\r
