Question

amys dog sleeps for 12 hours each night. she wants to know what percent of the day he sleeps.
what fraction shows the number of hours amys dog sleeps out of the total number of hours in the day? complete the fraction.
\frac{\square}{?}

Explanation:

Step1: Determine total hours in a day

A day has 24 hours.

Step2: Identify sleep hours and form fraction

The dog sleeps 12 hours. The fraction is $\frac{\text{sleep hours}}{\text{total hours in a day}}=\frac{12}{24}$. We can simplify it by dividing numerator and denominator by 12, getting $\frac{1}{2}$. But the question just asks for the fraction showing sleep hours out of total hours, so the numerator is 12 (sleep hours) and denominator is 24 (total hours in a day).

Answer:

The fraction is $\frac{12}{24}$ (or simplified as $\frac{1}{2}$). For the given blanks, the numerator is 12 and the denominator (the "?") is 24.
