Question

how do you tell if a number is rational or irrational/ can i have examples too ?

Answer 1

does the number ever end? if not its irrational.

Answer 2

pi is an example of an irrational number, because the decimal continues on forever and doesn't ever repeat

Answer 3

i forgot to mention, if it is a repeater, like 1/3 -> 0.3333333333333333 to infinity, it is rational.

Answer 4

or something like 0.13131313131313 - this is a repeat of 13

Answer 5

im a little confused rational= never end and vice versa?

Answer 6
