Understanding Rational and Irrational Numbers

Rational numbers are numbers that can be expressed as the ratio of two integers. For example, 3/4, 22/7, and -5/6 are all rational numbers.

A rational number is a number that can be expressed as the ratio of two integers, i.e. a number of the form $a/b$, where $a$ and $b$ are integers and $b$ is not equal to zero.

For example, 3/4, 22/7, and -5/6 are all rational numbers.

On the other hand, irrational numbers are numbers that cannot be expressed as the ratio of two integers, such as pi (π) or the square root of 2. These numbers have decimal expansions that go on indefinitely in a seemingly random pattern, and they cannot be written as a finite fraction.
