Rational numbers are a type of number that can be expressed as the ratio of two integers, where the denominator is non-zero. This means that rational numbers can be written in the form a/b, where a and b are integers and b is non-zero. Fractions and decimals are both examples of rational numbers, with fractions being written in the form a/b and decimals being written in the form 0.a1a2a3..., where a, b, and c are integers.

Are Rational Numbers the Same as Integers?

Why Rational Numbers are Gaining Attention in the US

Rational numbers can be expressed as the ratio of two integers, while irrational numbers cannot. Irrational numbers are examples of real numbers that cannot be written in the form a/b, where a and b are integers.

Rational numbers are relevant for anyone who needs to work with fractions and decimals, whether it's in a professional or personal capacity. This includes:
