Find the product :

$7\dfrac{1}{12} \times \dfrac{8}{17}$

$\Rightarrow 7\dfrac{1}{12} \times \dfrac{8}{17}\\[1em] \Rightarrow \dfrac{85}{12} \times \dfrac{8}{17}\\[1em] \Rightarrow \dfrac{85}{17} \times \dfrac{8}{12} \\[1em] \Rightarrow 5 \times \dfrac{2}{3} \\[1em] \Rightarrow \dfrac{10}{3}\\[1em] \Rightarrow 3\dfrac{1}{3}.$

Hence, $7\dfrac{1}{12} \times \dfrac{8}{17} = 3\dfrac{1}{3}$.
