A community has a total of 800 residents. If 25% are children, how many adults are there?

Step 1: Understand that the total number of residents in the community is 800.
Step 2: Know that 25% means 25 out of every 100 residents are children.
Step 3: Calculate 25% of 800. To do this, multiply 800 by 0.25 (which is the decimal form of 25%).
Step 4: Perform the multiplication: 800 * 0.25 = 200. This means there are 200 children.
Step 5: To find the number of adults, subtract the number of children from the total number of residents: 800 - 200.
Step 6: Perform the subtraction: 800 - 200 = 600. This means there are 600 adults in the community.
