Ratio of reactants

The following balanced equations represent double replacement reactions that each result in the formation of a precipitate. For each reaction, which ratio of reactants would result in the formation of the greatest amount of precipitate?

Cu(NO3)2 (aq) + 2NaOH(aq) --> Cu(OH)2 (s) + 2NaNO3 (aq) Note: Cu(OH)2 is a blue precipitate

FeSO4 (aq) + 2NaOH(aq) ---> Fe(OH)2 (s) - Na2SO4 (aq) Note: Fe(OH)2 is a dark green precipitate

Fe(NO3)3 (aq) + 3NaOH (aq) ---> Fe(OH)3 (s) + 3NaNO3 (aq) Note: Fe(OH)3 is a red-orange precipitate

I didn't understand what my teacher was trying to get at either. That's why I came here. I believe that you understood it better than I did! Thank you!

Hope so. Kind of a silly question.
