Answer 2

$\tt \red{Answer:-}$

First case:-

$\tt{ \frac{12}{7} + \frac{ - 13}{7} }$

$\tt{ = \frac{12 - 13}{7} }$

$\tt{ = \frac{ - 1}{7} }$

Second case:-

$\tt{ \frac{ - 27}{7} \times \frac{3}{5} }$

$\tt{ = \frac{ - 81}{35} }$

Third case:-

$\tt{ \frac{ - 1}{7} \div \frac{ - 81}{35} }$

$\tt{ = \frac{ - 1}{ \cancel7} \times \frac{ \cancel{35}}{ - 81} }$

$\tt{ = \red{\frac{5}{81} }}$

Therefore, the answer is 5/81.
