### Instruction: A church rings its bells every 15 minutes, the school rings its bells every 20 minutes and the day care center rings its bells every 25 minutes. If they all ring their bells at noon on the same day, at what time will they next all ring their bells together?  (Answer in the form AB:CD without am or pm, such as 08:00).### Response: So the LCM of 15, 20, and 25 is 300.
That means the bells will ring together again in 300 minutes.
Right, and 300 minutes is 5 hours.
So the bells will ring together again at 5:00 PM.
