You can put this solution on YOUR website! After ringing together 5 Bells begin to ring at intervals of 9 seconds, 6 seconds, 4 seconds, 10 seconds and 8 seconds respectively.
How many times the Bells will ring together in one hour starting from first time ringing together?
Find the least common multiple of 9, 6, 4, 10, 8
2*2*2*3*3*5 = 360
Find how many seconds in 1 hr: 60*60 = 3600
3600/360 = 10 times all 5 ring together
