3) Let's find the mixed ratio of the following ratios and let's identify the mixed
ratio and find if these are ratios of greater or lesser inequality or ratio of equality,
(a) 8:6, 3:6 and 26 : 13 (b): 3,.. to and 3 : 16
(c)8:5,7: 12 and 22: 13, (a) : 5, 7:2​

Answer 1

Step-by-step explanation:

3. The ratio of two quantities of different kinds is not possible.

For example, 4 metres : Rs 6 is inadmissible as the comparison is not possible.

4. Inverse ratio: If two ratios, the antecedent and the consequent of one are respectively the consequent and antecedent of the other, they are said to be ‘inverse ratio’ or ‘reciprocal’ to one another.

For example, the inverse ratio of

3: 4 is

4: 3 and the inverse ratio of

4: 3 is

3: 4 . The reciprocal of

\dfrac{2}{3} is

\dfrac{3}{2} and the reciprocal of

3 is

\dfrac{1}{3} .

Corollary: The product of a ratio and its inverse is always unity.
