Final answer:
To convert the infant's weight from pounds to kilograms, multiply the pounds by 0.4536 and convert the ounces to kilograms.
Step-by-step explanation:
To convert an infant's weight from pounds to kilograms, you can use the conversion factor that 1 pound is approximately equal to 0.4536 kilograms. First, convert the pounds to kilograms by multiplying 10 pounds by 0.4536. This gives you 4.536 kilograms. Next, convert the ounces to kilograms by dividing 4 ounces by 16 (since there are 16 ounces in a pound) and then multiplying by 0.4536. This gives you 0.1134 kilograms.
Finally, add the weight in pounds and the weight in ounces together to get the infant's weight in kilograms. In this case, it would be 4.536 kilograms + 0.1134 kilograms = 4.6494 kilograms. Rounded to the tenths place, the infant's weight is approximately 4.6 kilograms.
