$\huge\boxed{\fcolorbox{red}{#ffdfff}{ - 13/60}}$

We have,

$( \frac{1}{ - 12} ) + ( \frac{2}{ - 15} )$

$= \frac{( - 1)}{12} + \frac{( - 2)}{15}$

$= [ \frac{( - 1)}{12} \times \frac{5}{5} ] + [ \frac{( - 2)}{15} \times \frac{4}{4} ]$

$= \frac{( - 5)}{60} + \frac{( - 8)}{60}$

$= \frac{( - 5) + ( - 8)}{60}$

$= \frac{ - 5 - 8}{60}$

$= \frac{ - 13}{60}$

$= - \frac{13}{60}$
