\n" ); document.write( "\"63\" books every \"6\" hours=>\"63%2F6\"
\n" ); document.write( "\"+x\" booklets in \"9\" hours =>\"x%2F9\"\r
\n" ); document.write( "\n" ); document.write( "so, \"63%2F6=x%2F9\" and your answer is:\r
\n" ); document.write( "\n" ); document.write( "A) \"63%2F6+=+x%2F9\"
\n" ); document.write( "
\n" );
