\frac{2.20 lb.}{1 kg}

\frac{1 kg}{1.5 mg}

48.5 milligrams

109.1 milligrams

\frac{1.5 mg}{1 kg}

Explanation:

Step1: Convert pounds to kilograms

The conversion factor is $\frac{1\ kg}{2.20\ lb}$. For a 160 - pound man, his weight in kg is $160\times\frac{1\ kg}{2.20\ lb}\approx72.73\ kg$.

Step2: Calculate medicine dosage

The dosage rate is $\frac{1.5\ mg}{1\ kg}$. So the dosage is $72.73\ kg\times\frac{1.5\ mg}{1\ kg}= 109.095\ mg\approx109.1\ mg$.

Answer:

Multiply the man's weight in pounds by $\frac{1\ kg}{2.20\ lb}$ to get the weight in kilograms.
Next, multiply the man's weight in kilograms by $\frac{1.5\ mg}{1\ kg}$ to determine the dosage of medicine required.
The total amount of medicine the man should receive is about $109.1$ milligrams.
