Answer 1

To convert from pounds to milligrams, we can use the following conversion factors:

1 lb = 453592 mg

So, to convert 4.7 lb to mg, we can multiply by the conversion factor:

4.7 lb * 453592 mg/1 lb = 2,130,574.4 mg

Therefore, 4.7 lb is equal to 2,130,574 mg. Since the original value has three significant figures, the answer should also have three significant figures. Therefore, the final answer is 2.13 x 10^6 mg.
