A ratio is a set of numbers, each of which represents the proportion or size of a variable with respect to the other values. For example, a ratio of 3:2 means that for every 3 parts of the first variable, there are two of the second. 6:4 is the same ration as 3:2, as are all other multiples of these numbers.
A unit ratio is a ratio scaled down so that the lower value is 1. The above example of 3:2 would become 1.5:1. A ratio of 9:6:2 would become 4.5:3:1.
