3.The numbers a and b are called terms of the ratio where, a is called antecedent and b is called consequent.
4.In a ratio, the second term is called consequent. Thus, in b:a, a is called the consequent.
5.To know about the properties of ratios it's important to know that a ratio is a method to compare two quantities of the same kind with same unit; by dividing first quantity by the second. It is denoted by the colon ':'. The ratio of P to Q = P/Q, and it is represented as P : Q.
