The answers are 8.6 ounces, 9.4 ounces, and 8.5 ounces

Explanation:

To find how much each puppy weights simply add the weight they gained (2.1 ounces) to the weight of each puppy at one week old. The process to add the weights is shown below:

First Puppy

6.5 ounces (weight at one week old)  +  2.1 ounces (weight gained)

Align both numbers using the period as the reference and add

          6.5

+          2.1

          8.6  

The weigh of the first puppy is 8.6 ounces which can be rounded as 9 ounces (integer)

Second Puppy

Now, repeat the process

7.3 ounces +  2.1 ounces

           7.3

+          2.1

           9.4

The weigh of this puppy is 9.4 ounces or  9 ounces (integer) if rounded

Third Puppy

6.4 ounces +  2.1 ounces

           6.4

+          2.1

           8.5

The weight of the third puppy is 8.5 ounces which can be rounded as 8 ounces or 9 ounces (integers) depending on the rounding method.
