document.write( "Question 1135345: An engine has a 4.6 litre capacity cooling system. If the most ideal solution of antifreeze for this engine is a 55.1 % solution (a mix of 55.1 % pure antifreeze and 44.9 % water). How much pure antifreeze (in litres) must be combined with a 45.4 % solution to achieve 4.6 litres of the ideal solution?
