First, understand the reactants and products.
Aqueous solution of sodium hydroxide + aqueous solution of iron (III) nitrate -->solid precipitate of iron (III) hydroxide + aqueous solution of sodium nitrate

Change the reaction into symbols.
NaOH (aq) + Fe(NO3)3 (aq) --> Fe(OH)3 (s) + NaNO3

Balance the equation such that the number of reactants and number of products are in equilibrium.
3 NaOH (aq) + Fe(NO3)3 (aq) --> Fe(OH)3 (s) + 3 NaNO3

Thus, the first reaction is the final balanced reaction.
