a rational number is a number that can be expressed as a _________

Answer 1

A rational number is a number 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. In other words, a rational number can be written in the form \( \frac{a}{b} \), where \( a \) and \( b \) are integers and \( b \neq 0 \).
