@love10129151 @e.mccormick can you help?

e.mccormick · Answer

A ratio is a fraction.  For a number to be rational it must have a form with numbers on top and bottom of a fraction.  If that is not able to be done, then the number is irrational.

anonymous · Answer

so 1/3 is irrational?

e.mccormick · Answer

$\dfrac{1}{3}$ as a decimal is one that never ends, but it still has a fractional form.

e.mccormick · Answer

so $\dfrac{1}{3}$ is rational.  It can be represented as a ratio, a fraction.

e.mccormick · Answer

$\pi$ on the other hand, is never just one integer over another integer.  It has no known end.  It has no known fractional form with only integers.

Oh ok i get it now! thanks!

e.mccormick · Answer

np.

Real vs. Complex/Imaginary is another one like this.  Real, it can be graphed on the Carteasian plane in some way.  Complex/Imaginary, it can't.  That is one way of thinking of that concept.
