Answer:
12th day
Explanation:
We are given that George and Maria decided to create a garden in their backyard.
George works on the garden every third day and Maria works on the garden every fourth day.
We have to find that if they worked on the garden today ,the number until they would be work on the same day again
In order to find that day they would be work together we are finding lcm
We have to find the lcm of 3 and 4
Lcm =
=12
Hence, lcm of 3 and 4=12
Therefore, George and Maria work together on the 12th day again.
