The conversion factor is 0.225 lb/N

Therefore 150 lb = 150/0.225 = 667 N

The second question asks to convert weight to mass, and for this you have to assume a value for g. When g = 9.8 m/s^2 (as at the surface of the Earth), 1 kg has a weight of 2.2 lb. Therefore the mass os a 150 lb person is 150/2.2 = 68.2 kg.

You could also just divide the Newtons weight of the first part by g in m/s^2 to get mass in kg.
