Torque, Equilibrium, & Stability

Two children are sitting on a seesaw. If one child has a mass of (m1) =22.0 kg and sits 2.30 m from the center pivot:
(a) How far from the pivot must the second child (m2) = 30.0 kg sit for them to balance?
(b) What is the net upward force of the pivot on the seesaw? The seesaw has a uniform mass distribution of 25 kg.
