Find the equivalent winding resistance reactance and impedance

A 100 kVA, 1100/230 V, 50-Hz transformer has an HV winding resistance of 0.1 Ω and a leakage reactance of 0.4 Ω. The LV winding has a resistance of 0.006 W and a leakage reactance of 0.01 Ω. Find the equivalent winding resistance, reactance and impedance referred to the HV and LV sides. Convert these to pu values.
