Question 995189: A quart bottle contains a mixture that is 1/3 antifreeze, 2/3 water. A half gallon bottle contains a mixture that is 3/4 antifreeze, 1/4 water. The contents of the two bottles are poured into a gallon jug. What is the ratio (one integer to another, in the form a:b) of antifreeze to water in the jug?
I need to explain the process to solving this word problem - HELP!

Keep all volume units as GALLONS or their fractions, and keep track of how much volume of the antifreeze (as if pure) and the water.

The Quart:
%281%2F3%29%281%2F4%29%2Agallon antifreeze
%282%2F3%29%281%2F4%29%2Agallon water

The Half-Gallon:
%283%2F4%29%281%2F2%29%2Agallon antifreeze
%281%2F4%29%281%2F2%29%2Agallon water

ALL COMBINED

Antifreeze, %281%2F3%29%281%2F4%29%2B%283%2F4%29%281%2F2%29
1%2F12%2B3%2F8
2%2F24%2B9%2F24
11%2F24
Water, %282%2F3%29%281%2F4%29%2B%281%2F4%29%281%2F2%29
2%2F12%2B1%2F8
4%2F24%2B3%2F24
7%2F24

This new combined mixture is 11%2F24 gallons antifreeze and 7%2F24 gallons water. Ratio of antifreeze to water is 11:7.
