Initially the mixture is 7 parts. The final mixture can be understood of 9 parts, although
\n" ); document.write( "the parts will become different size.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Concentration of milk at start is $\"5%2F7\"$ , and concentration of milk wanted is $\"4%2F9\"$ .
\n" ); document.write( "Simple two-part mixture problem.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let x be how many parts milk to add to the start mixture.
\n" ); document.write( " $\"highlight%28%2856%285%2F7%29%2Bx%29%2F%28x%2B56%29=4%2F9%29\"$ .
\n" ); document.write( "Solve for x, the liters of milk to add.
\n" ); document.write( " \n" ); document.write( "
