Question

divide the sum of -13/5 + 12/7 by the product of -31/7 and -1/2​

Answer 1

Answer:

$-\frac{2}{5}$

Step-by-step explanation:

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

$-\frac{31}{7}$ × ( $-\frac{1}{2}$ ) = $\frac{31}{14}$

$-\frac{31}{35}$ ÷ $\frac{31}{14}$ = $-\frac{31}{35}$ × $\frac{14}{31}$ = $-\frac{2}{5}$
