The scale factor from the model of a human ear to the actual ear is 55:2. If one of the bones of the model is 8.25 centimeters long, how long is the actual bond of the human ear?

Given :
Ratio of model of a human ear to the actual ear = 55:2
bones of the model = 8.25
Modal of human ear/actual ear = 55/2
actual ear = 2/55 * modal of human ear
actual ear = 2/55 * 8.25
actual ear = 0.3
Thus, actual bone of human ear is 0.3
