One way: there is a 24% difference absolutely between the two solutions. The 61% is 2/3 of the way to 69%, so it should be 2/3 of the amount.\r
\n" ); document.write( "\n" ); document.write( "x=45%
\n" ); document.write( "150-x=69%
\n" ); document.write( ".45x+(150-x)*.69=150*0.61=91.5
\n" ); document.write( ".45x+103.5-.69x=91.5
\n" ); document.write( "-.24x=-12
\n" ); document.write( "x=50 liters of 45%
\n" ); document.write( "150-x=100 liters of 69%
\n" ); document.write( "(100/150) is 2/3.
\n" ); document.write( "
