To calculate the average weight of the kittens, you need to sum up the weights and then divide by the number of kittens.
The weights of the kittens are: 1.05, 1.2, 1.15, 1.2, and 1.4.
First, calculate the total weight: \[ 1.05 + 1.2 + 1.15 + 1.2 + 1.4 = 5.1 \]
Next, divide the total weight by the number of kittens (which is 5): \[ \text{Average weight} = \frac{5.1}{5} = 1.02 \]
Thus, the average weight of the kittens is 1.02 pounds.
