A sleep medication is available as 0.1 milligram caplets. The patient is advised by his physician to take 400 mcg at bedtime. How many caplets will he take?
The patient would take $\square$ caplets (Type an integer or a decimal)
Answer
Final Answer: The patient would take \(\boxed{4}\) caplets.
Step 1 ：The question is asking how many 0.1 milligram caplets the patient needs to take to reach a total of 400 micrograms.
Step 2 ：First, we need to convert the micrograms to milligrams because the caplets are measured in milligrams. 1 milligram (mg) is equal to 1000 micrograms (mcg). So, 400 mcg is equal to 0.4 mg.
Step 3 ：Then, we divide the total milligrams the patient needs to take (0.4 mg) by the milligrams per caplet (0.1 mg) to find the number of caplets.
Step 4 ：Let's calculate this: \( \frac{0.4 \, \text{mg}}{0.1 \, \text{mg/caplet}} = 4.0 \, \text{caplets} \)
Step 5 ：Final Answer: The patient would take \(\boxed{4}\) caplets.
