The clock shows half past midnight. What part of the day has passed?

To solve this problem, remember, in order to calculate what part is the number A of the number B, you need to divide the number A by the number B. When the clock shows half of the first night, that is 00:30, this means that 30 minutes have passed since the beginning of the day. Let’s convert minutes to hours. 1 hour = 60 minutes. 30 minutes = 0.5 hours. There are 24 hours in a day, let’s calculate what part is 0.5 hours from 24 hours.
0.5 / 24 = 1/2: 24 = 1/2 * 24 = 1/48.
Answer: 1/48.
