\n" ); document.write( "---------------
\n" ); document.write( "y = kx
\n" ); document.write( "10 = k*15
\n" ); document.write( "k = 10/15 = 2/3
\n" ); document.write( "----------------
\n" ); document.write( "y = (2/3)*6
\n" ); document.write( "y = 4
\n" ); document.write( "--------- It's correct
\n" ); document.write( "Or,
\n" ); document.write( "10:15::y:6
\n" ); document.write( "15y = 60
\n" ); document.write( "y = 4
\n" ); document.write( "-------- \n" ); document.write( "
