Bob was using a recipe for a large cake that requires two-thirds of a tablespoon of cinnamon. Instead of making one large cake, Bob decided to use the recipe to make six small cakes. How
much cinnamon should he used for each of the small cakes?

0.66 is what he used for one whole cake.
and if bob used that for 6 small cakes then it would mean you would divide 0.66 by 6, getting you 0.11 of a tablespoon for each small cake, being close to 1/10 of a tablespoon and being 11/100 of a tablespoon, hope it helped
