62. A newborn weighs 3,459 grams. There are 453.59 grams per pound. What is the infant's weight in pounds and ounces?
Answer: A
The infant's weight is 7lbs 10oz.
To convert the newborn's weight from grams to pounds and ounces, we first divide the weight in grams by the number of grams per pound. The calculation shows that 3,459 grams equals approximately 7.69 pounds, which translates to 7 pounds and 10 ounces.
A) 7lbs 10oz.
This option is correct as it accurately reflects the conversion of 3,459 grams to pounds and ounces. When calculated, 3,459 grams divided by 453.59 grams per pound gives approximately 7.69 pounds, which is equivalent to 7 pounds and 10 ounces after converting the decimal into ounces.
B) 10lbs 7oz.
This option is incorrect because it significantly overestimates the weight. The conversion from grams to pounds indicates that the newborn weighs less than 8 pounds, making 10 pounds an inaccurate representation of the infant's weight.
C) 13lbs 3oz.
This option is also incorrect as it greatly exceeds the actual weight of the infant. Given the original weight of 3,459 grams, which converts to just under 8 pounds, this option cannot possibly be correct.
D) 3lbs 13oz.
This option is incorrect as well, underestimating the infant's weight. The weight of 3,459 grams converts to a weight much higher than this, confirming that 3 pounds is not a feasible weight for the newborn in this scenario.
Conclusion
The correct answer, 7lbs 10oz, accurately represents the conversion of the newborn's weight from grams to pounds and ounces. All other options fail to reflect the proper conversion calculations, either underestimating or overestimating the infant's actual weight. Thus, option A stands as the only correct choice.
