Question

In the following question, select the number from the given options which follows the same relationship as shared between the first two numbers.

$\frac{1}{7}:\frac{1}{14}::\frac{1}{9}:?$

• A. $\frac{1}{88}$
• B. $\frac{1}{80}$
• C. $\frac{1}{81}$
• D. $\frac{1}{18}$

Answer 1

The correct option is D $\frac{1}{18}$

The first fraction is multiplied by half to obtain the second fraction.

$\frac{1}{7}:\frac{1}{7}\times \frac{1}{2}=\frac{1}{14}::\frac{1}{9}:\frac{1}{9}\times \frac{1}{2}=\frac{1}{18}$

$\frac{1}{7}:\frac{1}{14}::\frac{1}{9}:\frac{1}{18}$

$\therefore$ Correct answer is option $D$
