A child sits on one side of a teeter totter of length 7.60 m, a distance of 49.7 cm away from the end of the beam. The child has a mass of 21.6 kg. Her mother has a mass of 43.6 kg. How far away from her end does she have to sit in order for the teeter tooter to be exactly balanced?

Is the center of the board located as the fulcrum. If so, then distance from center to child*child's mass = distance from center to mother*mother's mass. Note that the distances given in the problem are from the end and not the center.
