To determine how many carbohydrates are in Sammy's entire avocado, you will use multiplication.
You multiply the number of servings (2.307) by the amount of carbohydrates per serving (13.5):
\[ \text{Total Carbs} = \text{Servings} \times \text{Carbs per Serving} = 2.307 \times 13.5 \]
So, the operation to use is multiplication.
