Learning how to divide can be a little challenging, but knowing some basic rules about dividing can help. In this lesson, you'll learn about the divisibility rules that apply to the number 10 while having fun with some real-life examples.

Divisibility Defined

Divisibility means you can evenly divide a number without there being anything left over. Your answer will always be a whole number. For example, when you split a sandwich with your brother, share a pack of gum, or make sure that you and your cousin each have the same number of french fries without any extra left over, you are working with a divisible number of items.

The Rule for 10

In order to apply the divisibility rule for 10, the digit that is last in a number has to be 0. This works whether the number is 70, 700, or 7,000. The rule also works if the numbers do not have 0 as a middle digit such as 210, 340, and 620. All of them are divisible by 10.

Any number that ends with a 0 is divisible by 10

Let's say you were at a party with 9 of your friends and had 150 goldfish crackers to divide among all 10 of you. After you were done counting out goldfish crackers, everyone would have the same amount without anything extra because 150 is divisible by 10. You know this because 150 ends with 0. So if it's a hot summer day and 10 people on your swim team want to share a box of 30 popsicles, dividing them evenly among 10 people is possible.

Practice Problems

Whether you are sharing french fries, cookies, or chips, you will always be able to share them evenly, as long as the digit you have ends with 0. Let's practice a few together.
