Divide :

$\dfrac{20}{31}$ ÷ 54

We have:

$\begin{array}{ll} \phantom{=} \dfrac{20}{31} ÷ 54 \\ = \dfrac{20}{31} \times \dfrac{1}{54} & [\text{Reciprocal of } 54 \text{ is } \dfrac{1}{54}] \\ = \dfrac{10}{31} \times \dfrac{1}{27} & \text{[Simplifying 20 and 54 ⇒ Divide by 2]} \\ = \dfrac{10 \times 1}{31 \times 27} \\ = \dfrac{10}{837} \end{array}$

∴ The answer is $\dfrac{10}{837}$
