Question

is 4/9 a rational number?

Answer 1

Yes, \( \frac{4}{9} \) is a rational number. A rational number is defined as a number that can be expressed as the quotient or fraction \( \frac{a}{b} \), where \( a \) and \( b \) are integers and \( b \neq 0 \). In this case, \( 4 \) is an integer and \( 9 \) is also an integer with \( 9 \neq 0 \), so \( \frac{4}{9} \) is indeed a rational number.
