\n" ); document.write( "Informally, the ratio of the percentages is 15:20 = 3:4, so the ratio of X and Y has to be 4:3 for the product to be the same.

\n" ); document.write( "Formally....
\n" ); document.write( "\".15X+=+.20Y\"

\n" ); document.write( "Solve for \"X/Y\" (the ratio of X to Y) by dividing both sides by .15Y:
\n" ); document.write( "\"X%2FY+=+.20%2F.15+=+4%2F3\"
\n" ); document.write( "
