Question

_____ is the sub-duplicate ratio of $\frac{1}{4}:\frac{1}{36}$

• A. $\frac{1}{4}:\frac{1}{6}$
• B. $\frac{1}{2}:\frac{1}{6}$
• C. $\frac{1}{6}:\frac{1}{2}$
• D. $\frac{1}{16}:\frac{1}{216}$

Answer 1

The correct option is B $\frac{1}{2}:\frac{1}{6}$

The subduplicate ratio of $\frac{1}{4}:\frac{1}{36}$ is $\sqrt{\frac{1}{4}}:\sqrt{\frac{1}{36}}=\frac{1}{2}:\frac{1}{6}$
