Answer 1

Answer:

My answer is fully different but I tried my best

So sorry for wrong answer

Step-by-step explanation:

$1st \: \: \: sum = \frac{ - 5}{7} + \frac{ - 8}{3} \\ \\ = \frac{ - 15 + ( - 56)}{21} = \frac{ - 71}{21} \\ \\ 2nd \: \: \: sum \: = \frac{5}{2} + \frac{ - 11}{12} \\ \\ = \frac{30 + ( - 11)}{12} = \frac{19}{12} \\ \\ subtraction \\ \\ = \frac{19}{12} - ( - \frac{71}{21} ) \\ \\ = \frac{19}{12} + \frac{71}{21} \\ \\ = \frac{133 + 284}{84} \\ \\ = \frac{417}{84} = 4 \frac{81}{84}$ cut 81 and 84 from 3 table then it will come 27/28

It is correct mark as brainliest

Answer 2

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

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

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

$⟹ \tt \red{\frac{139}{28} }$

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