Question 250905
First a definition:  A rational number is any number that can be expressed as a fraction in some way. Books often say a/b, where b cannot = 0.

we have 7/22 - since this is a fraction it is "rational"

3.14114111411114 . . . - here there is a pattern to the numbers, but it is not repeating the same pattern. This is "irrational".

{{{sqrt(2) + 8}}} - any time you have the square root of a prime number, it will never be rational. It is "irrational."
