Simplify :

$\dfrac{1.3 \times 2.4}{0.39}$

We have:

$\phantom{=} \dfrac{1.3 \times 2.4}{0.39} = \dfrac{3.12}{0.39} = \dfrac{3.12 \times 100}{0.39 \times 100} = \dfrac{312}{39}$

On dividing 312 by 39, we get:

$\begin{array}{r} 8 \ 39 \overline{\smash{)} 312 } \ \underline{312} \ 0 \end{array}$

Hence, the answer is 8.
