Question

What's the answer ???????

Answer 1

I would say the first one.
I'm not sure if the - sign on 0.3 is 0.3^- or not tho.

However, here's the fact "a rational number is a number that can be written as a ratio."
So for example, 8 is a rational number because it can be written as a fraction 8/1.
Irrational numbers are not rational. Like $\pi$ or $\sqrt{7}$(=2.645751....)

Hope this helps.
