Colin uses

cup of vegetable oil in each cake that he makes for his father's bakery. If Colin made 8 cakes, how much oil did Colin use in all?

5 1/3 see above

To find out how much oil Colin used in all, we need to multiply the amount of oil used in one cake by the number of cakes made.

Colin uses 2/3 cup of vegetable oil in each cake.

Therefore, to find the total amount of oil used, we multiply 2/3 by 8 (the number of cakes made):

(2/3) * 8 = (16/3) = 5 1/3 cups

So, Colin used 5 and 1/3 cups of vegetable oil in all the cakes he made.
