Problem #1: Antifreeze
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?
