• B. $2$
• C. $4$
• D. $-4$

Answer 1

The correct option is C $4$

On dividing$\frac{-22}{7}$ by a number, we get $\frac{-11}{14}$.

Let the required number be $x$.

$\Rightarrow \frac{-22}{7}÷x=\frac{-11}{14}$

$\Rightarrow$ $\frac{-22}{7}=x\times \frac{-11}{14}$

$\Rightarrow$ $\frac{-22}{7}÷\frac{-11}{14}=x$

$\Rightarrow$ $x=\frac{-22}{7}\times \frac{14}{-11}$

$\Rightarrow$ $x=4$

Hence, the required number is $4$.
