Question by  Smooti08 (23)

If a bell rings every 2 hours, a second bell rings every 3 hours, and a third bell rings every 4 hours. if all 3 bells ring at 9:00 am. , at what time will all 3 bells next ring?

I need help with a riddle.


Answer by  dertr (147)

At 9 pm. All the bells ring together every 12 hours, because 12 is the minimum common multiple of two, three, and four. So if the bells ring at 9 am, they will ring again at 9 pm.

They will ring again at the same time at 9:00 pm. if they rang at 9:00 am.

They will all ring every 12 hours, which is the first number divisible by 2, 3, and 4. If the bells all ring at 9 AM, then the next time they will ring is 9 PM.

It will ring again at 9:00 pm. if it rang at 9:00 am.

You need help with more than a riddle if you can't figure that one out, my friend. I hope you're in elementary school... otherwise there's just no excuse.
