Laura is baking a cake. The recipe says that she has to mix 64 grams of chocolate powder to the flour. Laura knows that 1 cup of that particular chocolate powder has a mass of 128 grams. She added two over three of a cup of chocolate powder to the flour. Should Laura add more chocolate powder to make the exact recipe, or did she go over and by what amount?

Question

$$128\div3=42.67$$So, 1/3 cup =42.67$$42.67\times2=85.333$$So, 2/3 cup =85.333

So, she went over by about 21.333 grams.
