yes. it is up to you to tell us how in depth you want us to go. as Plato asked you before, what axioms were you given? what have you done in class regarding this topic, how did your professor prove a similar problem? did he just do the simple algebra as i did, or did he take it step by step identifying each axiom as he went along? do you know what axioms are?no it is not wrong, it is just incomplete--i basically just did the steps, but you may be required to show how and why those steps work, and why is it valid for me to do what i did.so Jhevon answer is not wrong right??look at how we defined a rational number. it is a fraction made up of two integers where the bottom integer is not zero, doesn't b/a have that property as we defined it?I just don't get it b/a is also a rational number right?
