Q: In a study, 200 patients were infected with a virus. If 40% of them developed symptoms, how many patients showed symptoms?
Solution:
40% of 200 patients is 0.4 * 200 = 80 patients who developed symptoms.

Step 2: Convert 40% to a decimal. 40% as a decimal is 0.4.
Step 3: Multiply the total number of patients (200) by the decimal (0.4).
Step 4: Calculate 0.4 * 200, which equals 80.
Step 5: Conclude that 80 patients developed symptoms.
