If an eight-inch square cake serves four people, how many twelve-inch square cakes are needed to provide epuivalent servings to eighteen people?

The answer is 36 because i divided 8 to 4 so it would serve 2 people then multiplied by three to get 12 and that served 6 people so then multiplied by 3 to get 18 so u would need 36 cakes

11/2.2 = 5 inches for the length 8.5/2.2= 3.86 inches for the width
