If a national event is attended by 2,000 people and 60% are adults, how many are children?

If a national event is attended by 2,000 people and 60% are adults, how many are children?

Step 1: Find out how many adults are at the event by calculating 60% of 2,000.
Step 2: To calculate 60% of 2,000, multiply 0.60 by 2,000.
Step 3: The result of 0.60 * 2,000 is 1,200. This means there are 1,200 adults.
Step 4: To find out how many children are at the event, subtract the number of adults from the total number of people.
Step 5: Subtract 1,200 (adults) from 2,000 (total people): 2,000 - 1,200 = 800.
Step 6: Therefore, there are 800 children at the event.
