8 seconds respectively. In 90 minutes, how many times do they toll together

​

Answer 1

Answer:

Step-by-step explanation:

Answer: 3 times

Step-by-step explanation: we need to find LCM of 2,3,6,8 and LCM should be less than 90.

24, 48, 72, are their LCM < 90.

All toll together at 24, 48, 72, seconds, hence 3 times in 90 seconds.
