Sarah is making a healthy smoothie for breakfast. Her recipe includes 2 1/4 cups of yogurt. Sarah wants to make 3 servings. How much yogurt does she need in total?

To find the total amount of yogurt Sarah needs, we need to multiply the amount of yogurt for one serving by the number of servings.

Amount of yogurt for one serving = 2 1/4 cups
Number of servings = 3

Total amount = (2 1/4 cups) x (3 servings)
Total amount = 6 3/4 cups

Therefore, Sarah needs 6 3/4 cups of yogurt in total.
