How to find values with sub-duplicate ratio?
A ratio is a comparison of the sizes of two or more quantities of the same kind by division.
If p and q are two quantities of the same kind, then the fraction p/q is called the ratio of p to q.
The quantities p and q are called terms of the ratio.
Properties of Ratio:
The sub-duplicate ratio of a : b is √a : √b
