Answer 2

0.72 is not an irrational number.

Given:

A number 0.72

To Find:

We are required to find whether the given number is an irrational number or not.

Solution:

• An irrational number is a real number that cannot be expressed in fractions.

• A decimal number is an irrational number if its number keeps on repeating and has no end. (Ex: π is a rational number.)

0.72 is a decimal number but has ended and has no repeating values

So, 0.72 is a rational number.

Therefore, 0.72 is not an irrational number.
