Jeff is baking a cake. The recipe says that he has to mix 32 grams of vanilla powder to the flour.

sergeinik [125]

If 1 cup of that particular vanilla powder has a mass of 128 grams, then $\dfrac{2}{3}$ of a cup of vanilla powder has a mass of

$\dfrac{2}{3} \cdot 128=\dfrac{256}{3}=85\dfrac{1}{3}$ grams.

Since

$85\dfrac{1}{3}-32=53\dfrac{1}{3}$ grams and $\dfrac{5}{12}$ of a cup of vanilla powder is

$\dfrac{5}{12}\cdot 128=\dfrac{5\cdot 128}{12}=\dfrac{5\cdot 32}{3}=\dfrac{160}{3}=53\dfrac{1}{3},$

then correct answer is that he went over by $\dfrac{5}{12}$ of a cup.

Answer: correct choice is B.
