Is 0.144 rational or irrational ?
madam [21]
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.

I hope I was able to help you. Have a good day.
