What is a Rational Number: Understanding the Basics of Math - legacy
Rational numbers are only used in math
Not all decimals are rational numbers. For example, 0.123456... (repeating) is a rational number, but 0.123456... (non-repeating) is an irrational number.
Rational numbers can be expressed as a ratio of two integers, whereas irrational numbers cannot be expressed in this form. For example, 3/4 is a rational number, while π (pi) is an irrational number.
