The number of hours in a day is 24. The number of seconds in a day is $(24~h)(3600~s/h)$ We can calculate the ratio of the number of seconds in a day to the number of hours in a day. $ratio = \frac{\# ~of~seconds}{\# ~of~hours} = \frac{(24)(3600)}{24} = 3600$ The ratio of the number of seconds in a day to the number of hours in a day is 3600.
