1 1/2

3/4*2= 1 1/2

1 1/2÷1=1 1/2  ( a little clarification this reads one and one half)

I hope this is what you wanted:

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
