Homework Statement:

The center of mass of someone's thigh, shank, and foot are located at the following coordinates:
Thigh: (2.7, 3.2)
Shank: (2.1, 2.5)
Foot: (1.5, 1.9)
If the masses of them are respectively 9.6, 2.9, and 0.9 kg, where is the location of the entire leg?
ANSWER:
CM = (2.5, 3)
Relevant Equations:

CMx = Xprox + L%*(Xdist  Xprox)
CMy = Yprox + L%*(Ydist  Yprox)
CMbody = E*(CMseg*Mseg)/Mtotal

ANSWER:
CM = (2.5, 3)
I'm having trouble figuring out the steps for this. I feel like I need to know the Length % in order to complete the formula but am lost as to how to get this. Thank you for any help you may be.
