\n" ); document.write( "\n" ); document.write( "\"1kg%2A4dollar=x%2A9dollar\"\r
\n" ); document.write( "\n" ); document.write( "\"1kg%2A4cross%28dollar%29=9x%28cross%28dollar%29%29\"\r
\n" ); document.write( "\n" ); document.write( "\"%284%2F9%29kg=x\"\r
\n" ); document.write( "\n" ); document.write( "\"0.44444kg=x\"
