lena772 · Answer

If it's written as a ratio of two integers, so it's a rational number and not irrational. All rational numbers are real numbers, so this number is rational and real. Incorrect. Irrational numbers can't be written as a ratio of two integers.

Okay. I'm gonna ask you to close this question and post a new thread for further questions. It becomes a lot to scroll and violates the code of conduct to ask more than 1 question in a thread.

Yes PEMDAS. But I would just Distributive property first.
I also recommend posting each question in a different post or thread. It just makes it easier and doesn't make one thread too long.
