rational numbers

Rational numbers are numbers that can be expressed as a fraction, where both the numerator (the top number) and the denominator (the bottom number) are integers, and the denominator is not zero. This includes whole numbers, fractions, and negative numbers, as long as they fit this definition. For example, 1/2, 3, and -4 are all rational numbers. They can be represented on a number line and can be utilized in everyday situations, such as measuring, budgeting, and dividing items evenly. Ultimately, rational numbers are a vital part of the number system and our understanding of mathematics.
