Just like any other fractions.\r

\n" ); document.write( "\n" ); document.write( "\"%28a%2Fb%29%28c%2Fd%29+=+ac%2Fbd\" regardless of whether a, b, c, and/or d are numbers or polynomial expressions. Of course, the \"ac%2Fbd\" result may need to be reduced to lowest terms.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Likewise \"%28a%2Fb%29%2F%28c%2Fd%29+=+%28a%2Fb%29%28d%2Fc%29=+ad%2Fbc\". Again, the \"ad%2Fbc\" result may need to be reduced to lowest terms.\r
