Equation given:

$\boxed{ \sf \dfrac{8}{ - 15} \div \frac{4}{ - 3} }$

$\\$

Step by step explanation:

$\dashrightarrow\sf \dfrac{8}{ - 15} \div \dfrac{4}{ - 3}$

$\\$

$\dashrightarrow\sf \dfrac{8}{ - 15} \times \dfrac{ - 3}{4}$

$\\$

$\dashrightarrow\sf \dfrac{8}{\cancel - 15} \times \dfrac{\cancel - 3}{4}$

$\\$

$\dashrightarrow\sf \dfrac{2 \times \cancel4}{15} \times \dfrac{ 3}{\cancel4}$

$\\$

$\dashrightarrow\sf \dfrac{2}{15} \times \dfrac{ 3}{1}$

$\\$

$\dashrightarrow\sf \dfrac{2}{5 \times 3} \times \dfrac{ 3}{1}$

$\\$

$\dashrightarrow\sf \dfrac{2}{5 \times \cancel3} \times \dfrac{ \cancel3}{1}$

$\\$

$\dashrightarrow\sf \dfrac{2}{5}$

$\\$

$\dashrightarrow \boxed{ \sf0.4}$
