document.write( "Consider the three percentages 22, 50, and 100 on a number line.  The difference between 22 and 50 is 28; the difference between 50 and 100 is 50.  That means the two ingredients must be mixed in the ratio 28:50; since 50% is closer to 22% than it is to 100%, the larger portion must be the original liter (1000 ml) of 22% juice.<br><BR>\n" );
