\n" ); document.write( "4:7:9 is the same as 4x:7x:9x
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "4x + 7x + 9x = 120
\n" ); document.write( "20x = 120
\n" ); document.write( "x = 6
\n" ); document.write( "-----
\n" ); document.write( "4x = 24
\n" ); document.write( "7x = 42
\n" ); document.write( "9x = 54
\n" ); document.write( "-----------------
\n" ); document.write( "Classify::
\n" ); document.write( "54^2 > 24^2+42^2
