Given two XXXXXXXX XXXXXXX a and b XXXXX that XXX XXX XX rational:
The sum of any XXX XXXXXXXX XXXXXXX is XXXXXXXX.
XXXXX.
Suppose r and s are rational XXXXXXX. [XX must show XXXX r + s is XXXXXXXX.] Then, by XXX XXXXXXXXXX of XXXXXXXX numbers, we have
r = a/b XXX XXXX integers a and b with b ≠ X.
s = c/d XXX some integers c and d XXXX d ≠ 0.
So, XX substitution, XX XXXX
r + s = a/b + c/d
= (ad + XX)/bd
Now, XXX p = ad + bc and q = bd. XXXX, p XXX q are integers [XXXXXXX products and sums XX XXXXXXXX are integers XXX because a, b, c XXX d XXX XXX XXXXXXXX. Also, q ≠ 0 XX zero XXXXXXX XXXXXXXX.] Hence,
r + s = p/X , where p XXX X XXX XXXXXXXX XXX X ≠ 0.
Therefore, by XXXXXXXXXX XX a XXXXXXXX XXXXXX, (r + s) XX rational. This XX XXXX XXX XX XX shown.
XXX this completes the proof.

Part c:
