Is √0.0144 rational or irrational?

Answer 1

Irrational numbers can be written as decimals but not as fractions.

0.144 is a decimal, but it can also be written as 18/125. So this is a rational number.

√0.144 is equal to 0.3794733192. It cannot be expressed into a fraction. So, this is an irrational number.

√0.0144 is equal to 3/25. So, this is a rational number.
