Yes, 2/3 is a rational number because it can be written as a fraction with an integer numerator and a non-zero integer denominator. In the expression 2/3, the numerator is 2 and the denominator is 3, so it fits the exact definition of a rational number: any number that can be expressed as p/q, where p and q are integers and q ≠ 0.

Introduction
When people ask, “Is 2/3 a rational number?” they are usually trying to understand how fractions connect to the larger system of numbers in mathematics. The short answer is yes, but the longer answer helps explain why. Plus, rational numbers include integers, fractions, terminating decimals, and repeating decimals. Since 2/3 is a fraction made from two integers, it belongs clearly to the set of rational numbers.
No fluff here — just what actually works The details matter here..
It is also useful to distinguish 2/3 from numbers like π, √2, or 0.So naturally, 101001000100001…, which are irrational. These irrational numbers cannot be written as a simple fraction of two integers. By contrast, 2/3 can be written directly as a ratio, which is why it is rational Worth keeping that in mind..
What Does “Rational Number” Mean?
A rational number is any number that can be written in the form:
p/q
where:
- p is an integer
- q is an integer
- q is not equal to zero
The word rational comes from the idea of a ratio. Simply put, a rational number represents a relationship between two integers. For example:
- 1/2 is rational.
- 5/7 is rational.
- −4/9 is rational.
- 10/3 is rational.
- 0.75 is rational because it can be written as 3/4.
- 0.333… is rational because it can be written as 1/3.
The key point is that rational numbers are not limited to whole numbers. They include many numbers that fall between integers Less friction, more output..
