Yes, a half (1/2) is a rational number. A rational number is defined as any number that can be expressed as the quotient or fraction \( \frac{a}{b} \), where \( a \) is an integer and \( b \) is a non-zero integer. Since \( 1/2 \) fits this definition, it is classified as a rational number.
To clarify the comparison between a half and a whole number, a half is less than a whole number. For example, 1 (which is a whole number) is greater than 1/2. However, both are considered rational numbers.
