Question

Answer the question in side of blue box.

$divide \: the \: sum \: of \: \frac{ - 13}{5} \: and \: \frac{12}{7} \: by \: the \: product \: of \: \frac{ - 13}{7} \: and \: \frac{ - 1}{2}$

Answer 1

firstly add -13/5 and 12/7
So by adding -13/5 and 12/7
=-13/5+12/7
=-31/35
now multiply -13/7 and -1/2
=-13/7×-1/2
=13/14
now divide -31/35 and 13/14
=-31/35÷13/14
=-31/35×14/13
=-434/455
=-0.953846154 (answer)
