Mrs. Harrison used 16 ounces of dark chocolate while baking. She used 2/5 of the chocolate to make some frosting and used the rest to make brownies. How much more chocolate did Mrs. Harrison use in the brownies than in the frosting?
Chocolate used for frosting: 2/5 * 16 = 32/5.
Chocolate used for brownies: 3/5 * 16 = 48/5
Difference: 48/5 - 32/5 = 16/5.
Answer: 16/5 more ounces.
Thank you
