Question

Explain in step by step​

Answer 1

Answer:

3 times

Step-by-step explanation:

3 hrs

8 hrs

12 hrs

LCM of 3 & 8 = 24

LCM of 8 & 12 = 24

LCM of 3 , 8 & 12 = 24

LCM of 3 & 12 = 12

Hence two owls at a time at multiple of 12 but not multiple of 24

12 , 36 , 60

Three times

Answer 2

Step-by-step explanation: Factors of each

3: 3

8: 2 * 2 * 2

24: 2 * 2 * 2 * 3

LCM

2 * 2 * 2 * 3

24

All three owls will only hoot every 24 hours

Every other hour on the hour, except hour 24, at least one owl will not hoot

Therefor in 40 hours

At least one owl will not hoot 39 times <----
