You can put this solution on YOUR website!

document.write( "Instead of me just doing it for you, I'll do one EXACTLY like it.\r\n" );
document.write( "Then you can use it as a model to do yours.

\r\n" );
document.write( "x corresponds to 4 in the first proportion\r\n" );
document.write( "x corresponds to 3 in the second proportion.\r\n" );
document.write( "\r\n" );
document.write( "Get the LCM of 4 and 3 which is 12.\r\n" );
document.write( "\r\n" );
document.write( "So change the ratio 4:9 to the ratio 12:27 by multiplying 4 and 9 by 3\r\n" );
document.write( "Change the ratio 3:8 to the ratio 12:32 by multiplying 3 and 8 by 4\r\n" );
document.write( "\r\n" );
document.write( " x:y = 12:27 and x:z = 12:32\r\n" );
document.write( "\r\n" );
document.write( "Now that x corresponds to 12 in both proportions, y corresponds to 27\r\n" );
document.write( "and z corresponds to 32, so\r\n" );
document.write( "\r\n" );
document.write( " y:z = 27:32\r\n" );
document.write( "\r\n" );
document.write( "Now use that as a model and do yours exactly the same way.\r\n" );
