Answer:
The addition of any two rational numbers is a rational number.
Therefore, \frac{a}{b} + \frac{c}{d} is a rational number.
Step-by-step explanation:
Verification:
We have,
1) \frac{3}{4} + \frac{5}{7} = \frac{(3 X 7) + (5 X 4)}{28}
= \frac{(21 + 20)}{28} = \frac{41}{28}
which is a rational number.
2) \frac{-7}{12} + \frac{5}{6} = \frac{(-7) + (5 X 2)}{12}
= \frac{(-7 + 10)}{12} = \frac{3}{12} = \frac{1}{4}
which is a rational number.
