Problema Solution
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 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?
Answer provided by our tutors
128 *(2/3) = 85.3
85.3-64 = 21.3
so Laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams
