Let w be the mass in grams of water removed.
\n" ); document.write( "\"%28100%2A0.87-w%29%2F%28100-w%29=0.8\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"87-w=0.8%28100-w%29\"
\n" ); document.write( "\"87-w=80-0.8w\"
\n" ); document.write( "\"7-w=0.8w\"
\n" ); document.write( "\"7=w%2B0.8w\"
\n" ); document.write( "\"7=1.8w\"
\n" ); document.write( "\"w=7%2F1.8\"
\n" ); document.write( "\"w=3.9\" or \"w=3%268%2F9\"\r
