Tell weather the ratio from a porportion 6:2 and 12:!

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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
