Answer
$\frac{14}{15} $.
Work Step by Step
The given expression is
$=\left (\frac{-4}{5} \right )\div\left (-1\frac{1}{2} \right )-\left (\frac{2}{-5} \right )$
Change to customary form.
$=\left (-\frac{4}{5} \right )\div\left (-\frac{3}{2} \right )-\left (-\frac{2}{5} \right )$
Invert and multiply; cancel common terms.
$=\left (-\frac{4}{5} \right )\times\left (-\frac{2}{3} \right )-\left (-\frac{2}{5} \right )$
The product is positive.
$=\left (\frac{8}{15} \right )+\left (\frac{2}{5} \right )$
The LCD is $15$.
$=\left (\frac{8}{15} \right )+\left (\frac{6}{15} \right )$
$=\frac{8+6}{15} $
$=\frac{14}{15} $.
