Elanor’s newborn baby weighs 3,400 g. Convert the weight to pounds. Round to the nearest tenth of a pound.
The Correct Answer and Explanation is:
Answer:
Elanor’s baby weighs 7.5 pounds.
Explanation:
To convert grams to pounds, use the conversion factor:
1 pound = 453.592 grams.
Start by dividing the baby’s weight in grams by the number of grams in a pound: 3,400 g453.592 g/lb≈7.4957 lb\frac{3,400 \text{ g}}{453.592 \text{ g/lb}} \approx 7.4957 \text{ lb}453.592 g/lb3,400 g≈7.4957 lb
Next, round the result to the nearest tenth: 7.4957≈7.5 lb7.4957 \approx 7.5 \text{ lb}7.4957≈7.5 lb
This calculation shows that a 3,400-gram baby weighs approximately 7.5 pounds.
Grams are a metric unit used commonly around the world, especially in medical contexts. Pounds, on the other hand, are part of the imperial system often used in countries like the United States. For newborns, birth weight is a vital indicator of health. Nurses and pediatricians may use both grams and pounds depending on the regional standards of practice.
When converting between these units, accuracy is important, especially in medical records and reports. Rounding to the nearest tenth provides a balance between precision and readability, particularly for everyday discussions or documentation.
This example highlights how unit conversions support better communication and understanding across different measurement systems. Whether in hospitals, clinics, or conversations among family members, expressing weight in familiar terms helps people make sense of important health information.
In conclusion, Elanor’s baby, weighing 3,400 grams at birth, weighs approximately 7.5 pounds when rounded to the nearest tenth.
