An alloy of tin and copper has 6 pounds of copper for every 2 pounds of tin.
\n" ); document.write( "If 200 pounds of this alloy are made, how many pounds of tin are used?
\n" ); document.write( "---
\n" ); document.write( "6:2 is the same as 6x:2x where 2x is the amount of tin
\n" ); document.write( "-----
\n" ); document.write( "Equations:
\n" ); document.write( "2x + 6x = 200
\n" ); document.write( "8x = 200
\n" ); document.write( "x = 25
\n" ); document.write( "----
\n" ); document.write( "Amount of tin = 2x = 2*25 = 50 lbs.
