Answer:
7/12
Explanation:
Julie and Stefanie shared 1 whole candy bar. Therefore, the candybar can be represented as 1.
To find out what fraction of the candy bar Stefanie and Julie ate, simply add how much each girl ate.
Stefanie ate 1/4 and Julie ate 1/3. 1/4 + 1/3 = 7/12.
Therefore, Stefanie and Julie ate 7/12 of the candy bar. I hope this helps!
