Divide :

$13\dfrac{1}{3}$ ÷ 10

We have:

$\begin{array}{ll} \phantom{=} 13\dfrac{1}{3} ÷ 10 \\ = \dfrac{40}{3} ÷ 10 & \text{[Converting mixed to improper fraction]} \\ = \dfrac{40}{3} \times \dfrac{1}{10} & [\text{Reciprocal of } 10 \text{ is } \dfrac{1}{10}] \\ = \dfrac{4}{3} \times \dfrac{1}{1} & \text{[Simplifying 40 and 10 ⇒ Divide by 10]} \\ = \dfrac{4 \times 1}{3 \times 1} \\ = \dfrac{4}{3} \\ = 1\dfrac{1}{3} \end{array}$

∴ The answer is $1\dfrac{1}{3}$
