it would be A (117) because our output value is 225 then we represent our unknown value with X. 225 would equal to 100% and the X is pretty much the 52% we have in the equation. 225= 100% and X= 52%. Now, by dividing our first equation by the second equation, and knowing that both the RHS of both equations have the same unit, we have
225/x and 52/100.
The reciprocal for both sides give x= 117.
I really hope this wasn’t too complicated.
