Joe used 16 ounces of dark chocolate while baking. he used to fifths of the chocolate to make some frosting and use the rest to make brownies. how much more chocolate did joe used in the brownies then in the frosting?

He used 16 oz of dark chocolatehe used 2/5 to make frostingmeaning he used 3/5 for the brownies.

2/5(16) = 32/5 = 6.4 oz for frosting
3/5(16) = 48/5 = 9.6 oz for the brownies

Therefore, he used (9.6 - 6.4) = 3.2 more oz in the brownies then in the frosting
