\n" ); document.write( "---
\n" ); document.write( "y/x = 8/6
\n" ); document.write( "Y/X = Y/9
\n" ); document.write( "---
\n" ); document.write( "y/x = Y/X
\n" ); document.write( "---
\n" ); document.write( "8/6 = Y/9
\n" ); document.write( "Y = (9)8/6
\n" ); document.write( "Y = 12
\n" ); document.write( "---
\n" ); document.write( "answer:
