Answer :

To simplify 54 hours into a combination of hours and days, follow these steps:

1. Understand the basic units of time:
- There are 24 hours in one day.

2. Determine the number of full days in 54 hours:
- To find out how many full days there are, divide the total hours by 24.
- 54 ÷ 24 = 2 (full days)

3. Calculate the remaining hours:
- After accounting for the full days, calculate the remainder to see how many hours are left.
- The remainder when 54 is divided by 24 is 6.
- (54 ÷ 24 results in 2 days with a remainder of 6 hours)

4. Combine the results:
- The 54 hours can be expressed as 2 full days and 6 remaining hours.

Therefore, the simplified denominate number for 54 hours is 2 days and 6 hours.
