in order to balance the carrying pole, he must put it on his shoulder right on the equilibrium position

let point C be that position,

and let the distance from A to C is x, so the distance from C to B is (1.5 - x), in meters

we assume that A is the weight and B is the force

since:
weight * length of weight = force * length of force

then
5 * x  = 4,5 * (1,5 - x)
5x = 6,75 - 4,5x
9,5x = 6,75
x = 0,75

hence, he must put his shoulder right 0,75 meter from A

hope this is clear enough and helpful
