Explanation:

Step1: Convert pounds to kilograms

We know that 1 kg = 2.2 pounds. Let the weight in kilograms be $x$. Given the weight in pounds is 28 pounds. Then $x=\frac{28}{2.2}\text{ kg}$.

Step2: Calculate the dose of medicine

The dose of medicine is 5 milligrams per kilogram. So the dose $D = 5\times\frac{28}{2.2}\text{ mg}$.
$D=\frac{140}{2.2}\approx64\text{ mg}$

Answer:

64
