in essence what is \"%281%2F3%29%2B%281%2F5%29=%285%2F15%29%2B%283%2F15%29=8%2F15\"
\n" ); document.write( ":
\n" ); document.write( "so 8/15 of his money has been spent
\n" ); document.write( ":
\n" ); document.write( "meaning 7/15 of his money is left
\n" ); document.write( ":
\n" ); document.write( "\"%287%2F15%29%2845%29=315%2F15=highlight%2821%29\" dollars left for the big date.
\n" ); document.write( "
\n" );
