What percentage of a day is one hour and 45 minutes? A . 7.218% B. 8.3% C . 7.291% D . None of these

To calculate the percentage of a day that corresponds to 1 hour and 45 minutes, follow these steps:

Convert 1 hour and 45 minutes into hours:
Since 1 hour is already in hours, we convert 45 minutes into hours.
45 minutes = 45/60 hours = 0.75 hours.
Therefore, 1 hour and 45 minutes = 1 + 0.75 = 1.75 hours.

Calculate the total hours in a day:
A day has 24 hours.

Calculate the percentage:
To find the percentage of a day that 1 hour and 45 minutes represents, divide the time (1.75 hours) by the total hours in a day (24 hours) and multiply by 100.
(1.75 / 24) × 100 = 7.2917%.

So, the percentage is approximately 7.291%.
The correct answer is C. 7.291%.
