Questions & Step-by-Step Solutions
In a security drill, 60% of the participants were from the police department. If there were 200 participants, how many were from the police department?
Step 1: Understand that 60% means 60 out of every 100.
Step 2: Know that there are 200 participants in total.
Step 3: To find out how many participants are from the police department, we need to calculate 60% of 200.
Step 4: Convert 60% to a decimal by dividing 60 by 100, which gives us 0.60.
Step 5: Multiply 0.60 by 200 to find the number of police participants: 0.60 * 200.
