Every day, the Morgan Pet Store uses 1/2 of a bag of dog food to feed the dogs. How many days will 3 1/2 bags of dog food last?
Write your answer as a fraction or as a whole or mixed number.
3 1/2 bags of dog food would last for 7 days.
Each day, 1/2 of a bag of dog food is used, so 1/2 bag of dog food is used per day.
Therefore, to determine how many days 3 1/2 bags of dog food will last, you need to divide the total amount of dog food by the amount used each day:
3 1/2 / 1/2 = 7 days.
