Answer:
No
Explanation:
First of all, an irrational number is any number that can be changed into a fraction.
As you can see here, 4/3 is a fraction but some fractions, such as 4/2 or 12/3, can be simplified into integers, like 2 and 4. 4/3 is 1.5, and decimals are not integers, the biggest subset inside the set of rational numbers.
Irrational numbers are pi, square roots, etc.
