Adults need eight hours of sleep per day. What fraction of the day is this? Give your answer in simplest form.

We can identify that in our problem, we have these two pieces of information, eight hours of sleep is what they need per day. We also know that that means 24 hours. So, we can start with our fraction of eight twenty-fourths. We then need to reduce the fraction just like all the others we’ve practiced. Eight and 24 share a common factor of eight, so we’re gonna divide the numerator and the denominator by eight here. When you divide the numerator and the denominator by eight, you get the simplified fraction one-third. Based on the information given, that would mean that adults need to sleep one-third of the day.
