Mecchical Advantage = output / input MA = f out/ f in

Ideal Mechanical Advantage = length of inclined / height of inclined IMA = l/ h

Ideal Mechanical Advantage = Radius of input / Radius of output IMA = R in/ R out

Ideal Mechanical Advamtage = distance from input to fulcrum/ distance from output force to fulcrum IMA = d in/ d out
