what is the greatest common factor of the term in the expression 73/ ab - 7/ 6 b?

I tried solving it and I got an answer of 86c

Hope I helped!! :)

Step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
