If the two rational numbers are expressed as p/q and r/s, then their sum is (ps + rq)/(qs)
Every time. The sum of two rational numbers MUST be a rational number.
Add them together and divide by 2 will give one of the rational numbers between two given rational numbers.
The result will also be a rational number.
No. The set of rational numbers is closed under addition (and multiplication).
Another rational number.
no
Yes, it is.
Suppose the two rational numbers are x and y.Then (ax + by)/(a+b) where a and b are any positive numbers will be a number between x and y.
Not necessarily. The sum of two irrational numbers can be rational or irrational.
yes
There are no consecutive rational numbers. Between any two rational numbers there are an infinity of rational numbers.
Wrong because 3/4 and a 1/4 are rational numbers that add up to 1
