To determine whether a number is irrational or not, we need to understand the definition of irrational numbers.
An irrational number is a number that cannot be expressed as a simple fraction and has an infinite number of non-repeating decimal places or digits. In other words, irrational numbers cannot be written as a terminating decimal or a repeating decimal.
Now let's consider the given number, which is 1.5.
To determine if 1.5 is irrational, we need to check if its decimal representation is a non-repeating and non-terminating decimal.
The decimal representation of 1.5 is 1.5, which terminates after the digit 5. Since it is a terminating decimal, 1.5 is a rational number and not irrational.
Therefore, 1.5 is not an irrational number.
