As a professional writer, I understand the importance of providing valuable resources for students and teachers. That’s why I’ve created this comprehensive guide to help you understand and practice the divisibility rules with a worksheet.

What are Divisibility Rules?

Divisibility rules are a set of guidelines that help you determine if a number is divisible by another number without performing long division. These rules are based on the properties of numbers and can be applied to any integer.

How to Use Divisibility Rules?

Using the divisibility rules is easy. All you need to do is memorize the rules and apply them to the number you want to test. If the number passes all the rules, then it is divisible by the divisor.

For example, let’s say you want to test if 732 is divisible by 3. You would add up the digits of the number: 7+3+2=12. Since 12 is divisible by 3, then 732 is also divisible by 3.

Divisibility Rules Worksheet

Now that you understand the concept of divisibility rules, it’s time to practice with a worksheet. This worksheet includes a variety of problems to help you master the rules.
