Transcript text: A patient needs 0.024 g of a sulfa drug. There are $12-\mathrm{mg}$ tablets in stock. How many tablets should be given?
Express your answer as an integer.
$\square$ tablets
Solution
Solution Steps
Step 1: Convert grams to milligrams
The patient needs \( 0.024 \, \text{g} \) of the sulfa drug. Since \( 1 \, \text{g} = 1000 \, \text{mg} \), convert grams to milligrams:
\[
0.024 \, \text{g} \times 1000 \, \text{mg/g} = 24 \, \text{mg}.
\]
Step 2: Determine the number of tablets
Each tablet contains \( 12 \, \text{mg} \) of the sulfa drug. To find the number of tablets required, divide the total milligrams needed by the milligrams per tablet:
\[
\frac{24 \, \text{mg}}{12 \, \text{mg/tablet}} = 2 \, \text{tablets}.
\]
Step 3: Express the answer as an integer
The number of tablets required is \( 2 \), which is already an integer. No further rounding is needed.
