Explanation
Set up a ratio box.

Put the recipe’s original ratio of ingredients in the top row and start with 2 eggs in the “actual” row.
This makes your multiplier \(\frac{2}{3}\).
Fill out the rest of the ratio box to determine the number of cups of butter.
Hence \(\frac{1}{3}\) is correct!

A 1/2 is missing in the question where it says 'cups of butter'. Was wondering why it got my answer wrong (because I took 1 instead).
