Hey there!
-13/5 + 12/7 ÷ -13/7 ✖ -1/2
= -91+ 60 /35 ÷ 13/14
= -31/35 ✖ 14/13
= -31/5 ✖ 2/13
= -62/65
hope helped!

Answer:
Sum of (-13/5) and (12/7) = (-91+60)/35 = (-31/35) = (A) …(1)
Product of (-31/7) and (-1/2) = (-31/14) = (B)…(2)
Sum divided by the product = A/B
= (-31/35)*[14/(-31)]
= 14/35
= 2/5. Answer
