3.5 and -3.5 is one such pair.
3 and -3
No, all integers are rational, whole numbers.
If a set is closed under an operation. then the answer will be a part of that set. If you add, subtract or multiply any two rational numbers you get another national number. But when it comes to division, it is closed except for one number and that is ZERO. eg 3.56 (rational number) ÷ 0 = no answer. Since no answer is not a rational number, that rational numbers are not closed under the operation of division.

Yes. For example, the sum of 2 + √3 and 2 - √3 is 4.

All natural numbers are rational numbers.
No, all whole numbers are rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
All integers and fractions are rational numbers whereas irrational numbers can't be expressed as fractions as for example the square root of 2 can't be expressed as a fraction because it is a non-terminating decimal number.
Add them together and divide by 2 will give one of the rational numbers between two given rational numbers.
1 + sqrt(2) is irrational 1 - sqrt(2) is irrational. Their sum is 2 = 2/1 which is rational.

No, they are not. An irrational number subtracted from itself will give 0, which is rational.
