the ratio of cocoa beans to milk is 5 to 4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's presumably 5 pounds of cocoa beans to 4 gallons of milk.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "assuming that's true, then your ratio is c/m = 5/4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c = number of pounds of cocoa beans.
\n" ); document.write( "m = gallons of milk.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you have 80 pounds of cocoa beans, then c/m = 4/5 becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "80/m = 4/5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "cross multiply to get 5m = 4*80.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this becomes 5m = 320.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "divide both sides of this equation by 5 to get m = 64.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "80 pounds of cocoa beans requires 64 gallons of milk.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the ratio of 80 / 64 can be simplified to 5/4 by dividing both numerator and denominator by 16.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you get (80/16) / (64/16) = 5/4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
