To determine which sum results in a rational number based on the closure property of rational numbers, we need to remember that the closure property states that the sum (as well as the product and difference) of any two rational numbers is also a rational number.
A rational number is any number that can be expressed as the fraction \(\frac{a}{b}\), where \(a\) and \(b\) are integers and \(b \neq 0\).
If you provide specific sums or examples, I can help you evaluate each one to see which results in a rational number.
