Amy's dog sleeps for 12 hours each night. She wants to know the percent of the day she sleep. What fraction shows the number of hours Amyś dog sleeps out of the total number of the hours in a day? Complete the fraction

1/2

Step-by-step explanation:

What we must do is calculate the fraction of the hours of sleep with respect to the hours of a day.

We know that a day has 24 hours.

Now:

12 hours of sleep for the every 24 hours in a day, it would be:

12/24

Simplify to get 1/2

We know that 1/2 is equal to 0.5 or what is the same as he spends 50% of the time asleep.
