Answer: B.
$\frac1{45}*5=\frac19$

Explanation:

We know that,

(a)/(b)/(c)/(d)=(a)/(b)*(d)/(c)

Then,
$\frac19/ 5$
$=\frac19*\frac15$

$=\frac1{45}$

i.e.

$\frac19/ 5=(1)/(45)\\\\\Rightarrow\ \frac1{45}*5=\frac19 \ \ \ \text{[Multiply 5 on both sides]}$

Therefore, the multiplication equation is related to the division equation
$\frac1{45}*5=\frac19$

Hence, the correct option is B.
$\frac1{45}*5=\frac19$
