Final answer:
To convert pounds to milligrams, first convert pounds to kilograms by dividing by 2.20, then convert kilograms to milligrams by multiplying by 1,000,000.
Step-by-step explanation:
To convert pounds to milligrams, we need to follow the conversion process step by step. First, we know that 1 kilogram is equal to 2.20 pounds. So we can convert pounds to kilograms by dividing the given value of pounds by 2.20. In this case, 4.0 * 10⁻² pounds is equal to approximately 1.8181818 kilograms (rounded to 7 decimal places). Then, we know that 1 kilogram is equal to 1,000,000 milligrams. So, to convert kilograms to milligrams, we can multiply the value in kilograms by 1,000,000. Therefore, 1.8181818 kilograms is equal to approximately 1,818,182 milligrams (rounded to the nearest whole number). Therefore, 4.0 * 10⁻² pounds is approximately equal to 1,818,182 milligrams.
