If a user receives 200 emails in a week and deletes 50% of them, how many emails remain?

If a user receives 200 emails in a week and deletes 50% of them, how many emails remain?

Step 1: Start with the total number of emails received, which is 200.
Step 2: Calculate 50% of the emails. To find 50%, you can multiply 200 by 0.5 (which is the decimal form of 50%).
Step 3: Perform the multiplication: 200 * 0.5 = 100.
Step 4: The result, 100, is the number of emails that were deleted.
Step 5: To find out how many emails remain, subtract the number of deleted emails from the total: 200 - 100.
Step 6: Perform the subtraction: 200 - 100 = 100.
Step 7: Therefore, the number of emails that remain is 100.
