A church has 3 bells. One rings after every 3 minutes, the other after
every
4
minutes and the third one after every 5 minutes. If they all ring together at
8:00 a.m., at what time will they ring together again?

Answer:

9:22

Explanation:

Find the LCM Least common multiple of all three numbers (minutes)

3,4,5 LCM is 60

Divide each one into the LCM

60/3 = 20

60/4 = 15

60/5 = 12

Totals =82

add that to the time 8:00

82 is an Hour and 22 minute so it would be 9:22

I looked at other problems and this is how they solved it. I hope it helps
