    Answer: 9.6 ounces of butter, 8 ounces of sugar, 12 ounces of flour, 4 eggs

    Step-by-step explanation: 20 / 16 = 4/5. 16 is four-fifths of 20. So multiply 4/5 with everything.

    12 * 4/5 = 9.6 ounces

    10 * 4/5 = 8 ounces

    15 * 4/5 = 12 ounces

    5 * 4/5 = 4 eggs

    - 9.6 oz butter

    - 8 oz sugar

    - 12 oz flour

    - 4 eggs

    Step-by-step explanation:

    We know that for 20 cupcakes, we need the following amount for each ingredient:

    - 12 oz butter

    - 10 oz sugar

    - 15 oz flour

    - 5 eggs

    We now only want 16 cupcakes. To find how much of each ingredient we need, let's write a proportion for each. Say b is the amount of butter we need, s is the amount of sugar, f is flour, and e is eggs:

    16 cupcakes / 20 cupcakes = b oz butter / 12 oz butter

    16 cupcakes / 20 cupcakes = s oz sugar / 10 oz sugar

    16 cupcakes / 20 cupcakes = f oz flour / 15 oz flour

    16 cupcakes / 20 cupcakes = e eggs / 5 eggs

    These turn out to become:

    20b = 16 * 12 ⇒ b = 9.6 oz butter

    20s = 16 * 10 ⇒ s = 8 oz sugar

    20f = 16 * 15 ⇒ f = 12 oz flour

    20e = 16 * 5 ⇒ e = 4 eggs

    Thus, our answers are:

    - 9.6 oz butter

    - 8 oz sugar

    - 12 oz flour

    - 4 eggs
