Answer:
in short, Yes they are always rational.
here's why...
E.g. suppose 
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 
and since they are bound by addition (sum means addition) they must also be rational since eit would equal a bigger integer than initially had
Step-by-step explanation:
(23+15x) when you add this you will have your answer
84 is 60% of 140!
To get this answer, you have to do 84 x 100 and you get 8400: Then you divide 8400 by 60 and get 140.
Answer:
a and b bc that are in the negative-positive quad
