A ratio is a quantitative relationship between two numbers that describes how many times one value can contain another. The numbers in a ratio may be quantities of any kind, such as counts of persons or objects, or such as measurements of lengths, weights, time, etc. In most contexts both numbers are restricted to be positive, and the second to be not zero.
