In the context of proving that the sum of two rational numbers is rational, we need to pick a value for \( a \) that is a rational number.
Among the choices provided:
- 30 (this is a rational number)
- \( \frac{3}{0} \) (undefined, not a rational number)
- \( \pi \) (irrational number)
- \( \sqrt{3} \) (irrational number)
- 3 (this is also a rational number)
The values that could be used for \( a \) in order to apply the proof are **30** and **3**, as both are rational numbers.
If you are to choose just one, 30 is a valid rational number you could use for \( a \).
