Answer 1

$\huge\color{cyan}\boxed{\colorbox{black}{ANSWER ❤}}$

LCM of 2, 4, 6, 8, 10, 12 is 120

Means they would toll together each 120 seconds = 2 min

Now, how many times they toll toghether in 45 min?

We know that, they toll together each 2 min. So,

$45 \div 2 = 22$

They would toll together 22 times in 45 min.

Answer 2

The ans is 22 times:

The L.C.M of 2,6,8,10,12 is 120

45 mins = 2700 seconds

2700s / 120s = 22

Thus the bells will ring 22 times in 45 minutes.
