Question

9.) how many milligrams is 8.4 grams? 8.4 grams = ______ milligrams

Explanation:

Step1: Recall unit conversion factor

We know that \( 1 \text{ gram} = 1000 \text{ milligrams} \). This is the conversion factor between grams and milligrams.

Step2: Multiply by conversion factor

To convert \( 8.4 \) grams to milligrams, we multiply \( 8.4 \) by \( 1000 \). Mathematically, this is \( 8.4\times1000 \). When we multiply a number by \( 1000 \), we move the decimal point three places to the right. So, \( 8.4\times1000 = 8400 \).

Answer:

\( 8400 \)
