Question

Which multiplication equation is related to the division equation 1/9 ÷ 5 = __

Answer 1

Answer: B. $\dfrac1{45}\times5=\dfrac19$

Step-by-step explanation:

We know that,

$\dfrac{a}{b}\div\dfrac{c}{d}=\dfrac{a}{b}\times\dfrac{d}{c}$

Then, $\dfrac19\div 5$ $=\dfrac19\times\dfrac15$

$=\dfrac1{45}$

i.e.

$\dfrac19\div 5=\dfrac{1}{45}\\\\\Rightarrow\ \dfrac1{45}\times5=\dfrac19 \ \ \ \text{[Multiply 5 on both sides]}$

Therefore, the multiplication equation is related to the division equation $\dfrac1{45}\times5=\dfrac19$

Hence, the correct option is B. $\dfrac1{45}\times5=\dfrac19$
