Answer:


-2(3)/(8)

Explanation:

We are given the following fractions to divide:


\frac {\frac { -3 } { 4 } - \frac { 1 } { 5 } } { \frac { 2 } { 5 } }

Taking LCM of the fractions in the numerator to simplify it into a single fraction:


\frac { \frac { -15 - 4 } { 20} } {\frac {2} {5} }


\frac {\frac{-19} {20} } {\frac {2} {5} }

Taking reciprocal of the fraction in the denominator to change it to multiplication:


-(19)/(20) ×
(5)/(2)


-(19)/(8)

Changing this improper fraction into a mixed number:


-2(3)/(8)
