Answer 1

Pretty sure the next time they would ring together is 9 am

Answer 2

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
