Question

Sue made two types of cakes chocolate and vanilla. She cut all of the chocolate cakes into 5 slices each and all of the vanilla cakes into 15 slices each. If Sue ended up with the same total number of slices of each type of cake, what is the minimum number of slices of each type?

Answer 1

i think the answer is 5 because 15/5=3, and the 5 was the missing variable
