Answer 1

$the \: sum \: of \: 135 \: and \: - 127 \: is \\ 135 + ( - 127) = 8 \\ \\ product \: of \: - 317 \: and \: - 12 \: is \\ (- 317) \times ( - 12) = 3804 \\ \\ divide \: the \: sum \: of \: 135 \: and \: -127 \: by \: the \: product \: of \: - 317 \: and \: - 12 \: \\ 3804 \div 8 = \frac{951}{2} = 475.5$
