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
Find the arithmetic average of the two rational numbers. It will be a rational number and will be between the two numbers.
Wrong because 3/4 and a 1/4 are rational numbers that add up to 1
