To calculate the average weight of the kittens, you need to add up all 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 pounds.
-
First, add the weights together: \( 1.05 + 1.2 + 1.15 + 1.2 + 1.4 = 6.1 \) pounds.
-
Next, divide the total weight by the number of kittens (5): \( \frac{6.1}{5} = 1.22 \) pounds.
So, the average weight of the kittens is 1.22 pounds.
Since this exact value is not in the provided responses, the closest choice can be considered depending on rounding. If rounded to two decimal points, it might be acceptable to choose 1.2 as the response since it's the closest option listed.
