He added two over three 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?

Answer 1

Jeff went over by 53.33 grams or
`53(1)/(3)` grams.

Explanation:

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.

So, he added a mass of
`(2)/(3) *128= 85.33` grams of vanilla.

As the recipe says, it needs 32 grams of vanilla so Jeff went over by
`85.33-32=53.33` grams.

Jeff went over by 53.33 grams or
`53(1)/(3)` grams.
