If a national event is attended by 1,000 people and 20% are children, how many adults are present?

If a national event is attended by 1,000 people and 20% are children, how many adults are present?

Step 1: Identify the total number of people at the event, which is 1,000.
Step 2: Calculate the number of children by finding 20% of 1,000. To do this, multiply 1,000 by 0.20 (which is the decimal form of 20%).
Step 3: Perform the multiplication: 1,000 * 0.20 = 200. This means there are 200 children.
Step 4: To find the number of adults, subtract the number of children from the total number of people. So, 1,000 - 200 = 800.
Step 5: Conclude that there are 800 adults present at the event.
