Laura is baking a cake. The recipe says that she has to mix 64 grams of chocolate powder to the flour. Laura knows that one cup of that particular chocolate powder has a mass of 128 grams. She added 2/3 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

Mercury · Answer

1 cup of powder = 128 grams
so, 2/3 of a cup, is (2/3) of 128. evaluate what (2/3) of 128g, then see whether it's greater than, less, than, or equal to 64g, and by how much.
