**Explanation:**
To find the decimal of an hour that represents a second, we need to divide 1 hour by the number of seconds in an hour.
**Step 1: Convert 1 hour to seconds**
We know that there are 60 minutes in an hour and 60 seconds in a minute. So, to convert 1 hour to seconds, we multiply:
1 hour * 60 minutes/hour * 60 seconds/minute = 3600 seconds
**Step 2: Divide 1 by the number of seconds in an hour**
Now, we divide 1 by the number of seconds in an hour:
1 / 3600 = 0.000277778
**Step 3: Round the decimal to the nearest five decimal places**
Since the options provided are rounded to five decimal places, we need to round the decimal to match the options.
0.000277778 rounded to five decimal places is 0.00027
Therefore, the decimal of an hour that represents a second is 0.00027, which corresponds to option C.

To find the decimal of an hour that is equivalent to a second, we need to convert the units of time.
There are 60 seconds in a minute, and 60 minutes in an hour. So, there are 60 seconds in a minute * 60 minutes in an hour = 3600 seconds in an hour.
To find the decimal of an hour that is equivalent to a second, we need to divide 1 second by 3600 seconds.
Let's calculate it step by step:
Step 1: Convert 1 second to decimal form.
1 second = 1/60 minutes (since there are 60 seconds in a minute)
1/60 minutes = 1/60 × 1/60 hours (since there are 60 minutes in an hour)
1/60 × 1/60 = 1/3600 hours
Step 2: Simplify the fraction.
1/3600 hours is already in its simplest form, so we don't need to simplify it any further.
Step 3: Express the decimal form of 1/3600 hours.
To express the decimal form of 1/3600 hours, we divide the numerator (1) by the denominator (3600):
1 ÷ 3600 = 0.00027
So, the decimal of an hour that is equivalent to a second is 0.00027, which corresponds to option 'C'.
