Question

If two quantities have different units, then we can compare them by using the method of ratio.

• A. Ratio
• B. Proportion

Answer 1

The correct option is B

Proportion

If two quantities have different units, then we cannot compare them by the method of ratio. A ratio is a method of comparison of two similar quantities by using the method of division.
Example: The ratio of lengths of two cricket bats is 1 m and 90 cm, so we can compare their lengths by converting both the lengths into m or cm.
90 cm = 0.9 m, so the ratio is $\frac{1}{0.90}=\frac{10}{9}$
