+3 because in ionic compounds the oxidation numbers r crisscrossed. In this case the oxidation number of Oxygen is 2 (2 is in front of Fe) and oxidation number of Iron is 3 (3 is in front of Oxygen)

Oxidation State Of Fe2o3

2Fe2O3 + 3C -> 4Fe + 3CO2 The way to find the oxidation state is finding the number of oxygen atoms. Each has a charge of (-2). The Fe2O3 molecule is neutral, so this means the sum of all the charges have to cancel. 2*(+3) + 3*(-2) = 6 - 6 = 0. This is why the oxidation state of Fe is (+3).
