#### Answer

$\displaystyle \frac{11}{16}$

#### Work Step by Step

First, write mixed numbers as improper fractions,
Apply the equivalent fractions rule, $\quad \displaystyle \frac{a}{-b}=\frac{-a}{b}=-\frac{a}{b}$
$ \displaystyle \left(-\frac{11}{4} \right)\div\left(+\frac{8}{5} \right)\left(-\frac{2}{5} \right)$
Dividing with a fraction $\displaystyle \frac{a}{b} $ equals multiplying with the reciprocal, $\displaystyle \frac{b}{a}$
= $\displaystyle \left(-\frac{11}{4} \right)\cdot\left(+\frac{5}{8} \right)\left(-\frac{2}{5} \right)$
There are 2 minus signs in the product: the result is positive.
= $+\displaystyle \left(\frac{11}{4} \cdot\frac{5}{8}\cdot\frac{2}{5} \right)$
Reduce by the common factors, 5 and 2
= $\displaystyle \frac{11}{2} \cdot\frac{1}{8}\cdot\frac{1}{1} $
Now, multiply the numerators and place the product over the product of the denominators.
= $\displaystyle \frac{11}{16}$
