click done when you are satisfied with your answer.

Explanation:

Step1: Recall the conversion factor

We know that \(1\) milligram \( = 1000\) micrograms. So, to convert micrograms to milligrams, we divide by \(1000\). Dividing by \(1000\) is equivalent to moving the decimal point three places to the left.

Step2: Move the decimal point

Starting with \(250\) (which can be written as \(250.0\) in decimal form). Moving the decimal point three places to the left:

• For \(250.0\), moving the decimal point three places to the left gives \(0.250\)

Answer:

\(0.25\) milligrams
