Answer :
The correct answer is A. Loss of 8 oz, as it shows a greater weight change compared to the dog's weight loss of -7 oz.
The question is asking to compare different changes in weight to determine which shows a greater change when considering the dog's weight change of -7 oz while sick.
- A loss of 8 oz represents a greater weight change than a loss of 7 oz.
- A loss of 6 oz is less than the weight change of the dog.
- A gain of 6 oz is an increase in weight and therefore the opposite kind of change compared to the dog's loss.
- A gain of 3 oz is also an increase and less significant than the dog's weight loss.
Therefore, the correct answer is A. Loss of 8 oz, as it represents a greater decrease in weight compared to the dog's weight loss of -7 oz.
The greatest change in weight compared to -7 oz is a loss of 8 oz, since it has the largest magnitude when compared to the other options.
The student's question is related to changes in weight and involves understanding negative and positive numbers, as well as comparing their absolute values. A change of -7 ounces is being compared to various other changes to determine which shows a greater change in weight. When assessing weight changes, the negative sign indicates a loss, and no sign or a positive sign indicates a gain. To compare the changes, we need to consider the magnitude of the change without regard to whether it is a loss or gain.
Option A indicates a loss of 8 ounces, which is a greater change than a loss of 7 ounces.
Option B indicates a loss of 6 ounces, which is a smaller change than a loss of 7 ounces.
Option C indicates a gain of 6 ounces, which is also a smaller change than a loss of 7 ounces.
Option D indicates a gain of 3 ounces, which is the smallest change compared to a loss of 7 ounces.
Therefore, the correct answer is Option A, a loss of 8 ounces, as it represents the greatest change when compared to the original weight change of -7 ounces.
