Answer 1

$\huge\colorbox{pink}{Answer}$

$sum \: of \: \frac{ - 13}{5} and \: \frac{12}{7}$

$\frac{ - 13}{5} + \frac{12}{7} \\ \\ \frac{ - 91 + 60}{35} \\ \\ \frac{ - 31}{35} \\ \\ 0.88$

$product \: of \: \frac{ - 31}{7} \: and \: \frac{ - 1}{2}$

$\frac{ - 31}{7} \times \frac{ - 1}{2} \\ \\ \frac{ - 62}{ - 7} \\ \\ 8.8$

$divide \: the \: sum \: by \: product$

$\frac{0.88}{8.8} \\ \\ = 0.1$
