Answer 1

An irrational number is a number that does not have a end to it

if you mean √8, root 8 does not have a end to it, so it is irrational
pi, or (π) also does not have an end to it
144 - √  does not work as an expression, so it is not an answer
which leaves 0.45, which is rational, because it is terminated already

hope this helps
