Question

Find the sub-duplicate ratio of $9:16$.

Answer 1

Calculate the sub-duplicate ratio of the given ratio

Given ratio: $9:16$.

It is known that, if the ratio is $a:b$ then the sub-duplicate ratio is given by $\sqrt{a}:\sqrt{b}$.

Thus, the sub-duplicate ratio of $9:16$ is $\sqrt{9}:\sqrt{16}=3:4$.

Therefore, the sub-duplicate ratio of the $9:16$ is $3:4$.
