Answer:In a week, Sally drinks 28 cups of milk
Explanation:
In a day Sally drinks one and one third cups of milk 3 times which is equal to
1 1/3 x 3
4/3 x 3 =4 cups per day
1 week =7 days
therefore if she drinks 4 cups of milk in a day
in 7 days she will drink 4 x 7 =28 cups
In a week, Sally drinks 28 cups of milk
