ratio and proportion ii summary

Summary - Ratio is the numerical relationship between two quantities of the same kind. The first quantity is called the antecedent and the second quantity is called the consequent. By performing simple operations on ratios, we get compounded ratio, ..

Ratio: If a and b are two quantities with the same units such that b is not equal to zero; then the quotient a/b is called the ratio between a and b. It is written as a:b. Ratio does not have any unit. The quantities a and b are called terms of the ratio..

1. In a:b, a is called antecedent and b is called consequent. 2. Two or more quantities are said to be in continued proportion if the ratio of the first to the second is equal to the ratio of the second to the third and so on. ..
