In comparing two quantities of the same kind, the fraction, which expresses by how many times the first quantity is greater or smaller than the second quantity is called the ‘ratio’ between the first quantity and the second quantity. The mathematical symbol of ratio is ‘:‘ It is written as say, 1:4 and read as 1 “is to” 4. The first of the two quantities forming a ratio is called the antecedent and the second is called the consequent of the ratio. The two together are called the terms of the ratio. Points to Note: 1. Since the q…
