    A) The question would be, "how much of the FULL bag of fertilizer was recently used?"

    b) "What is the total amount of toober pus that is needed for the entire (all 4) batch of potion?"

    c) "How many pieces of pizza did Tommy eat?"

    Paul ate \frac{5}{16} of the brownies that had \frac{3}{4} cups of butter. Therefore, he consumed a total of \frac{3}{4}*\frac{5}{16} = \frac{15}{64} cups of butter when eating his portion of brownies.
