Question

Instead of three bells, suppose that we have six bells, which start ringing together, and then ring at intervals of 2,4,6,8,10 and 12 minutes respectively. In 30 hours, how many times will they ring together?

Answer 1

Answer:

hlo

your answer is here !

Step-by-step explanation:

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

Answer 2

Answer:

we would first take their LCM

=120

WHICH MEANS THEY WOULD RING TOGETHER IN EVERY 120 MINUTE

SO, NOW WE WOULD DIVIDE IT WITH 30 HOURS( OR 1800 MINUTE) =1800/120

=15

ANSWER IS IT WILL RING 15 TIMES
