Multiplying and Dividing Decimals

Learn all about multiplying decimals and dividing decimals in this free basic math lesson.

Dividing decimals

Let's look at a different situation. Let's imagine you have a fence, and you want to plant 5 bushes in front of it. Your fence is 20 feet long. You'd like to space the bushes out equally, so you know you'll need to divide your fence into 5 equal sections. This means you'll need to divide 20 by 5.

In the lesson on division, we learned how to set up division expressions. For the situation above, the expression would look like this:

In our expression, 20 is a whole number. But what if the length of the fence is a decimal number? For instance, let's say it's 20.75 feet long. Believe it or not, dividing a decimal isn't that different.

When you set up an expression to divide a decimal number, it's important to make sure you're always dividing by a whole number. In our example above, 20.75 is being divided by the whole number 5. Dividing by a whole number makes long division easier to manage.
