Frank is making salad dressing for a large party. If a serving is 2 1/2 tablespoons, how many servings can he make with 8/5 tablespoons?

To find the number of servings Frank can make, we need to divide the total amount of salad dressing by the amount per serving.

8/5 tablespoons / 2 1/2 tablespoons/serving = (8/5) / (5/2) = (8/5) * (2/5) = 16/25

Therefore, Frank can make 16/25 servings.
