To find the average weight of the kittens, you need to sum up their weights and divide by the number of kittens.
Sum of weights = 1.05 + 1.2 + 1.15 + 1.2 + 1.4 = 5.0
Number of kittens = 5
Average weight = Sum of weights / Number of kittens = 5.0 / 5 = 1.0
Therefore, the average weight of the kittens is 1.0 pound.
