Every day, the Roy Family Restaurant serves 7/10 of a bottle of soda to their customers. How many days will 4 9/10 bottles of soda last? Write your answer as a fraction or as a whole or mixed number.
To find out how many days 4 9/10 bottles of soda will last, we need to divide the total amount of soda by the amount served each day.
4 9/10 bottles can be expressed as an improper fraction: 4 * 10 + 9 = 49/10 bottles.
Now, we need to divide 49/10 by 7/10 to find the number of days it will last:
(49/10) / (7/10) = 49/10 * 10/7 = 49/7 = 7.
Therefore, 4 9/10 bottles of soda will last for 7 days at the Roy Family Restaurant.
