A newborn weighs 8 pounds 5 ounces. There are 453.59 grams per pound. What is the infant's weight in grams?

Rationale

3770 grams is the infant's weight in grams.

To convert the newborn's weight from pounds and ounces to grams, first convert the total weight into pounds and then to grams using the conversion factor. The total weight of 8 pounds 5 ounces converts to 8.3125 pounds, which when multiplied by 453.59 grams per pound equals approximately 3770 grams.

A (2268 grams) YOUR ANSWER

This option is incorrect because it significantly underestimates the weight of the newborn. To arrive at this figure, one would have to incorrectly convert the weight or fail to account for the full weight in pounds and ounces.

B (3629 grams) YOUR ANSWER

This choice also miscalculates the newborn's weight. It suggests a conversion error in either the pounds to ounces or the grams conversion process, resulting in a weight that does not accurately reflect the sum of 8 pounds and 5 ounces.

C (3770 grams) CORRECT

This is the correct answer as it accurately reflects the conversion of 8 pounds 5 ounces to grams. The calculation proceeds as follows: first, convert the ounces to pounds (5 ounces = 0.3125 pounds), then sum this with the 8 pounds for a total of 8.3125 pounds, and finally multiply by 453.59 grams to achieve 3770 grams.

D (3856 grams) YOUR ANSWER

This option is also incorrect, overestimating the newborn's weight. A mistake in the conversion from pounds to grams or in the addition of the weight components may have contributed to this figure, leading to a value that does not correspond to the actual weight.

Conclusion

The correct conversion of the newborn's weight from pounds and ounces to grams results in a total of 3770 grams. Understanding the proper conversion process is crucial, as miscalculations can lead to significant discrepancies in weight reporting. By ensuring that each step of the conversion is accurately followed, the true weight of the infant can be determined correctly.
