Jeff is baking a cake. The recipe says that he has to mix 32 grams of vanilla powder to the flour. Jeff knows that 1 cup of that particular vanilla floor has a mass of 128 grams. He added 2/3 of a cup of vanilla powder to the flower. Should Jeff add more vanilla powder to make the exact recipe, or did he go over and by what amount?

Answer :

The situation above described that Jeff added two - thirds of 128 to the flour. The numerical value of (2/3)(128) is 85.33 grams. The recipe says to add only 32 grams of vanilla flour.

Hence, Jeff went over the prescribed amount.

To determine the excess amount, subtract 32 from 85.33 which has a numerical value of 53.33 grams.
