Set up a ratio.\r

\n" ); document.write( "\n" ); document.write( "\"%2810cm%5E3%29%2F%2812+g%29+=+%2819+cm%5E3%29%2F%28x+g%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since \"a%2Fb=c%2Fd\" means \"ad=bc\",\r
\n" ); document.write( "\n" ); document.write( "the above equation can be written \"10x=12%2A19\"
\n" ); document.write( "\"10x=228\"
\n" ); document.write( "\"x=22.8\" g\r
