Final answer:
To make 8 cupcakes instead of 20, Deepak needs: 4.8 ounces of butter, 8 ounces of sugar, 5 ounces of flour, and 2.5 eggs.
Step-by-step explanation:
To find out how much of each ingredient Deepak needs to make 8 cupcakes instead of 20, we can set up a proportion using the number of cupcakes as the basis of comparison.
Let's start with the butter: 12 ounces of butter are needed for 20 cupcakes. We can set up the proportion:
12 ounces / 20 cupcakes = x ounces / 8 cupcakes
Cross multiplying, we get: 20x = 12 * 8. Solving for x, we find that Deepak needs 4.8 ounces of butter for 8 cupcakes.
Following the same process, we can determine the amounts of sugar, flour, and eggs needed for 8 cupcakes.
For sugar: 8 ounces of sugar
For flour: 5 ounces of flour
For eggs: 2.5 eggs (since eggs cannot be divided, Deepak can use 2 eggs and roughly half of the third egg).
