Answer: 5%
Step-by-step explanation:
First and foremost, we need to know that 60 minutes = 1 hour. Therefore,
7 hours = 60 × 7 = 420 minutes.
Number of minutes awake = 21 minutes
Number of minutes supposed to be asleep = 7 hours = 420 minutes
The percentage of the seven hours that Frank was awake during the night will be:
= 21/420 × 100
= 1/20 × 100.
= 5%
The answer to your problem is 4.32.
