balance the equation
2Al2O3>>4Al + 3O2
figure the moles of aluminum oxide in 155g
so you get twice those moles of aluminum.
Covert that to grams.

155g of Al203, molar mass is 101.96g/mol, number of moles is 1.52.
ration 2to4 2x=4(1.52)=3.04 moles.
mass = molar mass of Al is 26.98 times number of moles 3.04 = 82.019
