Hello there!

0.8 is not irrational

If a number can be written with a perfect fraction, it is rational

Hope I helped!

Let me know if you need anything else!

An irrational number is "a number that cannot be represented by a simple fraction, and usually goes on forever."

8/10 is the same as 0.8 (a terminated decimal) and so it is rational

hope this helps
