Q
Q: Which of the following numbers is prime?
Solution: 11 is only divisible by 1 and itself, making it prime.
Steps: 6
Step 1: Understand what a prime number is. A prime number is a number greater than 1 that can only be divided by 1 and itself without leaving a remainder.
Step 2: Look at the number 11. We need to check if it can be divided by any other numbers besides 1 and 11.
Step 3: Check if 11 can be divided by 2. It cannot, because 11 is odd.
Step 4: Check if 11 can be divided by 3. When you divide 11 by 3, it does not result in a whole number.
Step 5: Check if 11 can be divided by 4, 5, 6, 7, 8, 9, or 10. None of these divisions result in whole numbers.
Step 6: Since 11 can only be divided by 1 and itself (11), we conclude that 11 is a prime number.
