A rational number is defined as the quotient of two integers, where the denominator is non-zero. In the expression a/b + c/d, both b and d are non-zero, therefore, they fulfill the requirement for being the denominators of rational numbers. Additionally, the sum of two rational numbers is also a rational number.
Since a/b and c/d are both rational numbers, their sum a/b + c/d will also be a rational number.
In the proof that a/b + c/d where a, b, c, and d are integers and b and dare non-zero, explain why rational number. (1 point)
