Final answer:
Jill should bring two-fifths (0.4) of a pie to school each day to have the same amount of pie for 10 days.
Step-by-step explanation:
Jill's mom made 4 pies for dessert for the week, and Jill wants to bring a slice of pie to school every day for the next 10 days. To find out how much pie she should bring each day, we need to divide the total number of pies by the number of days she plans to bring pie to school. We calculate the fraction of pie she should bring each day as follows:
- First, determine the total amount of pie available: 4 pies.
- Next, divide 4 pies by 10 days to find the amount of pie for each day: 4 pies / 10 days = 0.4 pies per day.
- Therefore, Jill should bring 0.4 of a pie to school each day.
This means that every day, Jill will have the same amount of pie, which is two-fifths of a pie (0.4 of a pie equals 2/5 of a pie).
