$\tt\huge\red{A}\pink{n}\orange{s}\green{w}\blue{e}\gray{r}$

$\tt \huge\frac{85}{78}$

$\tt\huge\red{explanation}$

$\tt \huge \: \frac{9}{ - 26} + \frac{14}{39} + \frac{ - 5}{ - 13}$

$\tt \huge \: lcm \: = 78$

$\tt \huge \frac{9 \times 3}{26 \times 3} = \frac{27}{78}$

$\tt \huge \frac{14 \times 2}{39 \times 2} = \frac{28}{78}$

$\tt \huge \frac{ - 5 \times - 6}{ - 13 \times - 6} = \frac{30}{78}$

$\tt \huge \frac{27}{78} + \frac{28}{78} + \frac{30}{78} \\ \\ \tt \huge = \: \frac{24 + 28 + 30}{78} \\ \\ \tt \huge =\: \frac{85}{78}$
