Divide:

$2\dfrac{17}{38} ÷ 1\dfrac{12}{19}$

Solving,

$\Rightarrow 2\dfrac{17}{38} ÷ 1\dfrac{12}{19}\\[1em] \Rightarrow \dfrac{93}{38} ÷ \dfrac{31}{19}\\[1em] \Rightarrow \dfrac{93}{38} \times \dfrac{19}{31}\\[1em] \Rightarrow \dfrac{93}{31} \times \dfrac{19}{38}\\[1em] \Rightarrow 3 \times \dfrac{1}{2}\\[1em] \Rightarrow \dfrac{3}{2}\\[1em] \Rightarrow 1\dfrac{1}{2}.$

Hence, $2\dfrac{17}{38} ÷ 1\dfrac{12}{19} = 1\dfrac{1}{2}$.
