In this shorts video we will answer a standardized math test question where we are asked to identify which of four number values is irrational. We will learn that any nonperfect square number is irrational. We will also review that any value that can be written as a fraction is rational. Any decimal value that repeats or terminates is rational.

Know that there are numbers that are not rational, and approximate them by rational numbers.
CCSS.MATH.CONTENT.8.NS.A.1
Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.

Thank you, this helps this momma of an honors math grader. I am having to relearn a lot of math to help him study. This helped immensely.

Hello, thank-you so much for the video, and explanation. But what does "non perfect squares" mean?

Can you please explain because -0.19 can be writen as -19/100
So it will be also rational.
