All of the following are irrational except _____.
a_sh-v [17]

The number that is not irrational is 1.\overline{45}. The correct option is the second option 1.\overline{45}

<h3>Irrational numbers </h3>

From the question, we are to determine which of the given options is not irrational

Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q, where p and q are integers.

1.\overline{45}  is a repeating decimal and it can be expressed as a fraction

1.\overline{45} = \frac{144}{99}

∴ 1.\overline{45} is not an irrational number. It is a rational number

The other options cannot the expressed as a fraction.

Hence, the number that is not irrational is 1.\overline{45}. The correct option is the second option 1.\overline{45}
