ratio solved examples

Introduction - This chapter takes us much further and adds to our already existing knowledge about Ratio and Proportion. We will have to use many of the algebraic manipulations learnt earlier, use them with expertise to solve problems in this chapt..

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, duplicate ratio..

Ratio is the numerical relation of one quantity to another of the same kind. To find the ratio of 2 m 25 cm to 75 cm, we first change 2 m 25 cm into cm, which equals 225 cm. Now, we have to find 225 cm to 75 cm ratio is = 3 : 1 We can write the above ratio as..

If two or more ratios are multiplied term-wise, the ratio thus formed is called their compounded ratio..

The compounded ratio of three equal ratios is called their triplicate ratio. The triplicate ratio of a:b is a 3 :b 3..

The ratio a 2 : b 2 , obtained by compounding the ratio a : b with itself is called the duplicate ratio, . For example, the duplicate ratio of 4 : 9 is 4 2 : 9 2 = 16 : ..

When two or more ratios are multiplied with each other, the resultant simplified ratio is called the compounded ratio. Let a : b and c : d be two given ratios, then the compounded ratio is = ac : b..

It is ratio of women to men expressed as % of women in total population or number of women per every 1000 men. Sex ratio is a comprehensive indicator of women population ignoring their age, reproductive potentiality etc. Such sex ratio can indicate many national priori..

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. a' is called a..

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..
