Answer 2

$\frac{ {5}^{ - 1} + {3}^{ - 1} }{ {5}^{ - 1} - {3}^{ - 1} }$

$= \frac{ \frac{1}{5} + \frac{1}{3} }{ \frac{1}{5} - \frac{1}{3} }$

$= \frac{ \frac{3 + 5}{15} }{ \frac{3 - 5}{15} }$

$= \frac{ \frac{8}{15} }{ \frac{ - 2}{15} }$

$= \frac{8}{15} \times \frac{15}{ - 2}$

$= \frac{8}{ - 2}$

$= - 4$
