Answer 1

Step-by-step explanation:

Hello user,

_________________________

$\tt \frac{ - 5}{7} + \frac{ - 8}{3} = \red{\frac{ - 71}{21} }$

__________________________

$\tt \frac{5}{2} + \frac{ - 11}{12} = \red{\frac{19}{12} }$

__________________________

Now, subtract

$So, \: \tt \red{ \frac{19}{12} - \frac{ - 71}{21} }$

$⟹ \tt \red{\frac{ \cancel{ 317} ^{139} }{ \cancel{84}^{28} } }$

$⟹ \tt \red{\frac{139}{28} }$

$⟹ \tt \red{4 \frac{27}{28} } \: Ans.$
