Answer:
in short, Yes they are always rational.
here's why...
E.g. suppose  and
 and  are fractions, that means that a,b,c,d are all integers, and b and d are not zero. finding the sum the numerator, and denominator would also have to be integers. the denominator of the sum can't be zero since the denominators of the fractions were not zero, and would give
