Answer 2

Answer: Irrational

Step-by-step explanation: Notice that the decimal in this problem does not terminate which means it does not end.

Therefore, in order to decide whether it is rational or irrational, we need to determine whether the decimal is a repeating decimal. A repeating decimal is a non-terminating (non-ending) decimal in which one or more of the digits repeats.

There is a pattern to the digits, 27, 227, 2227, 22227, and so on but they're not exactly the same in every group. So there is no way to put a bar over any group of numbers to indicate that this is a repeating decimal.

Therefore, ur decimal is non-terminating and non-repeating which means that is must be an irrational number.
