The problem asks if 23,311 is divisible by 5 without performing actual division.

To determine if a number is divisible by 5, you simply check the last digit of the number. A number is divisible by 5 if and only if its last digit is either 0 or 5.

In this case, the last digit of 23,311 is 1, which is neither 0 nor 5. Therefore, **23,311 is not divisible by 5**.

Would you like more details on divisibility rules or any other concepts? Here are some follow-up questions for you:

1. How do you check if a number is divisible by 2 or 3?
2. What is the rule for determining if a number is divisible by 10?
3. Can a number be divisible by both 5 and 10 at the same time? Why or why not?
4. What other divisibility rules do you find useful for quick checks?
5. How can divisibility rules simplify calculations in larger problems?

**Tip:** Memorizing divisibility rules for small numbers like 2, 3, 5, and 10 can greatly speed up mental math!

Without dividing, determine if 23,311 is divisible by 5 and explain how you know.

Learn how to determine if 23,311 is divisible by 5 using divisibility rules. This problem involves recognizing that a number is divisible by 5 if its last digit is 0 or 5. Suitable for students in Grades 4-6.
