Question

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 powder has a mass of 128 grams. He added 2/3 of a cup of vanilla powder to the flour. Should Jeff add more vanilla powder to make the exact recipe, or did he go over and by what amount? (1 point)

Answer 1

Since 128/32 is 4, that means that 32 goes into 128 4 times and 32 grams is 1/4th of a cup. (2/3)*128=256/3=85+1/3 is the amount of grams he put in, so he went over by (85+1/3)-32=53+1/3 grams
