Three bells ring at intervals of 5
minutes, 6 minutes and 10 minutes.
They will ring together once in
minutes.
Answers
Answer:
In problems of such, we consider the least common multiple (LCM) of the three numbers; 5, 6, 10 which is 30 - hence they ring together again at 8:30. In other words, they ring together every 30 minutes.
Answer:
30 minutes
Step-by-step explanation:
For this question, we need to find the LCM of 5, 6, and 10 to find the earliest time when they will ring together.
To find the LCM we can either prime factorize and multiply the factors or multiply 5, 6, and 10 together. I have taken the second method as it is easy for me.
So, 5 * 6 * 10 = 300
I am dividing 300/10 as we have a thirty in the 10 table also and we needn't go so far as the number is too big.
So, by dividing 300/10 I get 30 which is their LCM.
In the first I have said that we have to find the LCM of 5, 6, and 10 to get the earliest time when they will ring together. Since we have found our LCM we have found our answer that is 30 minutes.
