First, I would convert the dimensions to inches.
\n" ); document.write( "--------
\n" ); document.write( "13 ft 5 in = \"+13%2A12+%2B+5+=+161+\" in
\n" ); document.write( "15 ft 9 in = \"+15%2A12+%2B+9+=+180+\" in
\n" ); document.write( "--------
\n" ); document.write( "Note that \"+161%2F7+=+23+\"
\n" ); document.write( "and \"+180%2F7+=+25+%2B+5%2F7+\"
\n" ); document.write( "--------
\n" ); document.write( "So you've got 23 tiles along one wall and
\n" ); document.write( "25 and 5/7 of a tile along the other wall
\n" ); document.write( "\"+23%2A25+=+575+\" is the number of whole
\n" ); document.write( "7\" tiles you need
\n" ); document.write( "Now you need 23 more tiles which you will
\n" ); document.write( "cut 2/7 off to get the 5/7 you need
\n" ); document.write( "---------
\n" ); document.write( "So now you have 575 + 23 = 598 tiles
\n" ); document.write( "which is the number you must buy\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
