Frank decided to keep track of his sleep using a fitness tracker. He was surprised to learn that there was 21 minutes of awake time during the seven hours when he was
supposed to be asleep at night. What percentage of the seven hours was Frank awake during the night?
%

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%

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
