What is a rational number?

anonymous · Answer

Can you tell me?

dangerousjesse · Answer

A rational number has a finite set of digits... Do any of these numbers have lines over them?

anonymous · Answer

nope

dangerousjesse · Answer

Then we'll say $\frac{x}{y}$ and $y\neq 0$ but $y=\textsf{an integer}$

Which of these numbers cannot be divided by an integer to form a finite number?

Let's say $\frac{x}{2}$ when $x=\textsf{the choices given}$ Any irrational number will have an impossible quotient (ex, 3.1415926535897932384626433832795028841971693993751 or $\pi$)
