Answer:  \frac{1}{2}

Step-by-step explanation:

First, let us simplify this part : [ (\frac{-8}{13})^-1   + (\frac{16}{5} )^-1]

(\frac{-8}{13})^-1 = \frac{-1}{8} ÷ \frac{1}{13}

          ⇒ \frac{-1}{8}× \frac{13}{1} = \frac{-13}{8}

(\frac{16}{5} )^-1 = \frac{1}{16} ÷ \frac{1}{5}

        ⇒ \frac{1}{16} ×\frac{5}{1}

        ⇒ \frac{5}{16}

So,  [ (\frac{-8}{13})^-1   + (\frac{16}{5} )^-1]  = \frac{-13}{8} + \frac{5}{16}

                                    = \frac{-26+5}{16}

                                    = \frac{-21}{16}

Next(\frac{4}{5})^-1,  =  \frac{1}{4} ÷ \frac{1}{5}

                  =  \frac{1}{4} × \frac{5}{1}

                 = \frac{5}{4}

Hence,  [ (\frac{-8}{13})^-1   + (\frac{16}{5} )^-1] ÷ (\frac{4}{5})^-1 =  \frac{5}{16}  ÷ \frac{5}{4}

                                                       ⇒\frac{5}{16}  × \frac{4}{5}

                                                        ⇒ \frac{1}{2}

Hope it helps!! Plz mark my answer as brainliest!
