Answer 2

Duration of the First Quarter

The first quarter lasts for 9 weeks. To calculate the number of calendar days in 9 weeks, we need to know the number of days in a week. The standard number of days in a week is 7.

Therefore, the number of calendar days in 9 weeks is calculated as follows:

9 weeks * 7 days/week = 63 calendar days.

Number of School Days

To calculate the number of school days in the first quarter, we need to know the number of days in a school week. You mentioned two scenarios: a 5-day school week and a 6-day school week.

For a 5-day school week, the number of school days in the first quarter is:

9 weeks * 5 days/week = 45 school days.

For a 6-day school week, the number of school days in the first quarter is:

9 weeks * 6 days/week = 54 school days.

Number of Days in Four Weeks

The number of days in four weeks is calculated as follows:

4 weeks * 7 days/week = 28 days.

Number of Days in Seven Weeks

The number of days in seven weeks is calculated as follows:

7 weeks * 7 days/week = 49 days.

Number of Weeks in a Given Number of Days

To calculate the number of weeks in a given number of days, we divide the total number of days by 7.

For 56 days:

56 days / 7 days/week = 8 weeks.

For 42 days:

42 days / 7 days/week = 6 weeks.

For 63 days:

63 days / 7 days/week = 9 weeks.

I hope this helps! Let me know if you have any further questions.
