Sandy's Ice Cream Corner uses 9/10 of a bag of cups every day. How many days would 10 bags of cups last?

10 / (9/10)

10 * (10/9) = 100/9 = 11.1

To find out how many days 10 bags of cups would last, we need to divide the total number of cups in 10 bags by the number of cups used per day.

First, we need to calculate the number of cups in one bag. If Sandy's Ice Cream Corner uses 9/10 of a bag of cups every day, then we have:

Number of cups in one bag = (9/10) * 1 bag = 9/10 bag

Now, let's calculate the total number of cups in 10 bags:

Total number of cups in 10 bags = (9/10 bag) * 10 bags = (9/10) * (10) bags

Now we can cancel out the common factor of 10:

Total number of cups in 10 bags = (9/10) * (10/1) bags = 9 cups

So, there are 9 cups in 10 bags.

Next, we can calculate how many days 10 bags of cups would last by dividing the total number of cups (9) by the number of cups used per day:

Number of days = Total number of cups / Cups used per day
Number of days = 9 cups / (9/10 cup per day)

Now, let's divide:

Number of days = 9 cups / (9/10 cup per day) = (9 cups) * (10/9) day per cup = 10 days

Therefore, 10 bags of cups would last for 10 days.

To find out how many days 10 bags of cups would last, we need to determine how many bags are used per day.

Given that Sandy's Ice Cream Corner uses 9/10 of a bag of cups every day, we can consider this as the usage rate per day.

To find the number of days 10 bags would last, we need to divide the total number of bags by the usage rate per day.

Number of days = Total number of bags / Usage rate per day

Let's calculate it:

Total number of bags = 10 bags
Usage rate per day = 9/10 of a bag

Dividing 10 bags by 9/10 of a bag can be done by multiplying 10 by the reciprocal of 9/10:

Number of days = 10 bags * (10/9) = (10 * 10) / 9 = 100 / 9

Therefore, 10 bags of cups would last approximately 11.11 (rounded to two decimal places) days at Sandy's Ice Cream Corner.
