\"+300%2F16+\" miles/gallon = \"+715%2Fx+\" miles/gallon
\n" ); document.write( "\"+300%2F16+=+715%2Fx+\"
\n" ); document.write( "Multiply both sides by \"+16x+\"
\n" ); document.write( "\"+300x+=+16%2A715+\"
\n" ); document.write( "\"+300x+=+11440+\"
\n" ); document.write( "\"+x+=+38.1333+\" gallons needed
\n" ); document.write( "
\n" );
