Answer: the sum of the two ingredients is 3 5/8
Step-by-step explanation:
Emily is baking a cake she added 1 3/8 cups of butter. Converting 1 3/8 cups of butter to improper fraction, it becomes 11/8 cups of butter.
She also added 2 2/8 cups of flour to a mixing bowl. Converting 2 2/8 cups of flour to improper fraction, it becomes 18/8 cups of flour.
Therefore, the sum of the ingredients that was added to the mixing bowl would be
18/8 + 11/8 = 29/8 = 3 5/8
