Best ResponseYou've already chosen the best response.0Just out of curiosity are you avoiding doing homework by yourself. You should try to challenge yourself. Not that its any of my business. Anyways if a number is rational it has a finite number of digits, so it terminates. If it is irrational it has a continuous infinite amount of digits. An easy way to tell is to look at the question and ask yourself, when i solve this will the answer be finite or infinite? For\[\sqrt{1.21}\] just because there is a decimal does not mean it is irrational if 1.1 is squared we will get 1.21. Hope this helps lol.
