Question

(d+8/d-9)divided by 9d+72/c-7

Can anyone point me in the right direction to solving this problem? Thank you

Answer 1

Your nonuse of grouping symbols is annoying.

I think you meant this:

(d+8)/(d-9) divided by (9d+72)/(c-7)

well, multiplication is reciprocal of division, so your problem becomes
(d+8)/(d-9) multiplied by (c-7)/(9d-72)
or

(d+8)(9d-72)/((d-9)(c-7) or

9(d+8)(d-9)/((d-9)(c-7)) or
9(d+8)/(c-7)
