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%

Using the quadratic formula, we have:

$\frac{1+- \sqrt{11} }{2}$ , so our solutions are $\frac{1+ \sqrt{11} }{2}$ and $\frac{1- \sqrt{11} }{2}$ .
