Compound and Inverse Ratio




Compound Ratio

Ratios are compounded by multiplying together the Antecedents for a new Antecedent and the Consequent for a new Consequent.


Example:

Let 3:2, 4:5, 2:7 are the three Ratios.

The multiplication result of the Antecedents of these three ratios is = 3 x 4 x 2 = 24

And

the multiplication result of the Consequent of these three ratios is = 2 x 5 x 7 = 70

The resultant Compound Ratio = 24:70 = 12:35




Inverse Ratio

If the Antecedent and Consequent of a simple ratio changes their place with each other, then the resultant ratio is called the Inverse of that ratio.


Example:

Let, 10:13 as a simple ratio.

Then 13:10 is the Inverse ratio of 10:13.



Note:

Previously we discuss about simple Ratios.

Ratio between two or more than two quantities are also possible.

Example:

The Ratio of the Length,width and height of a house is(All in metre) = 9:7:6
