Questions & Step-by-Step Solutions
In a study, 60% of patients with a certain disease were found to have a specific symptom. If 150 patients were studied, how many patients had the symptom? (2023)
Step 1: Understand that 60% means 60 out of every 100 patients.
Step 2: We need to find out how many patients out of 150 have the symptom.
Step 3: Convert 60% to a decimal. 60% as a decimal is 0.6.
Step 4: Multiply the total number of patients (150) by the decimal (0.6).
Step 5: Calculate 0.6 × 150, which equals 90.
Step 6: Conclude that 90 patients had the symptom.
