19:00 or 7:00 PM

Step-by-step explanation:

Baby armadillos need to be fed every four hours.

Baby bats need to be fed every three hours.

So we need to figure out when will they be fed again at the same time:

Basically, we need to find the LCM of two numbers i. e. 4 and 3. And the reason why are we finding the LCM is because that time difference will is the least common multiple of both the time differences, it is the smallest non-zero number that is the multiple of both 4 and 3.

The LCM of 4 and 3 is 12. So the time when they will be fed again at the same time will be 12 hours after 7:00 AM that is 19:00 hours or 7:00 PM.
