Introduction to Decimals

In this intro to decimals lesson, you'll get to fully understand them before adding, subtracting, multiplying, dividing, and converting them.

Reading decimals

As you saw on the last page, decimals look a lot like a regular numbers, with a few important differences. First, all decimals have a decimal point (.). The decimal point looks like a period. Any number to the left of the decimal point is a whole number. The numbers to the right are like a fraction—they're less than 1 whole but more than 0.

For example, let's take a look at this decimal.

9.6

9 is on the left of the decimal point, so we have 9 whole things. 6 is on the right, so we also have 6 parts of a whole.

We see written decimals all the time in real life. For example, you might know that the average body temperature is 98.6 degrees. Or you might tune in to a radio station like 97.5. But do you know how to read these decimals out loud?
