6 eggs in 7 days

Did the hen take a day off?
12 eggs in 14 days
18 eggs in 21 days
I doubt if you want the average of 6/7 of an egg per day. 
12 eggs in 14 days = 1.16667 convert it to 17 because you have to round...and 1.16 is rounded to 17...6 is higher than 5 so you can bring it up. So your answer is 17.
18 eggs in 21 days = 1.16667 is the same to answer number 1. Convert it to 17 and that is your answer!
