** a) Explain why n div 7 equals the number of complete weeks in days.**

**b) Explain why n div 24 equals the number of complete days inn hours.**

- It is explained that n div 7 equals the number of complete weeks in n days.
- It is explained that n div 7 equals the number of complete days in n hours.

* a | b (a divide b) ***there is an integer c such that b = ac .**

It is given that

Total days are n

We know a week has 7 days

If we divide the total days by 7, we get the number of weeks in n days

And if we take the integer part of this number, we will get the complete weeks in days.

hence n div 7 equals the number of complete weeks in n days.

It is given that

Total hours are n

We know a day has 24 hours

If we divide the total hours by 24 , we get the number of days in n hours

And if we take the integer part of this number, we will get the complete days in n hours

Hence, n div 24 equals the number of complete days in n hours.
