Arestaurant makes vegetable soup using 22 cups of mixed vegetables and 15 cups of stock. henri tries to make this at home with 5 cups of mixed vegetables and 10 cups of stock. is henri using the correct ratio? explain

He is doing it wrong because the restaurant uses 22 cups mixed veggies and 15 cups stock. 5 cups of mixed veggies is equal to ( (5/22) × 15 ), which is ~ 3.4 cups of stock and not 10.
The ratio should be 22: 15
or in terms of the question ~7.3 : 5

Ithink the answer is $2.10
