Answer:
The L.C.M. of 9, 12, and 15 will give us the minutes after which the bells will next toll together. So, the bells will toll together after 180 min.

Answer:
L.C.M ( 9,12,15)
9 = 3 x3
12 = 2 x 2 x 3
15 = 3 x 5
L.c.m ( 9,12,15) = 3x3x2x2x5 = 180 min or 3 hours.
∴ After 3 hours they toll together.
