Question

Is the following number rational or irrational?

Answer 1

Answer:

Rational

Step-by-step explanation:

To find out whether it is rational or irrational let's write the definitions of both

Rational: Any number that can be written as a fraction, integer, whole number, natural number

Irrational: Numbers that can't be written as a fraction

This has to be rational because every rational number can be written as a repeating decimal.

Answer 2

$6.\overline{6}=6\dfrac{2}{3}=\dfrac{20}{3}$

Since it can be expressed as fraction, it's a rational number.
