Answers

Answered by jenninath2019

Step-by-step explanation:

In 30 minutes, how many times do they toll together ? The least common multiple (LCM) of 2, 4, 6, 8, 10, and 12 is 120. Thus, the bells toll together every 120 seconds (or 2 minutes), so in 30 minutes they will toll simultaneously 30/2 = 15 times
