Solution

The correct option is B 3
Alex is preparing a recipe that requires 2/3 cups of oils per serving.

Alex needs to prepare 4 and 1/2 servings.

Let’s convert 4 ½ to an improper fraction.

= (4 × 2 + 1)/2 = 9/2

Let’s multiply both.

= ⅔ × 9/2

= (2 × 9)/(3 × 2)

= 18/6

= 3

Therefore, Alex needs 3 cups of oil.

Hence, (a) is correct.
