Unfortunately, the browser used by this site for posting questions is all but useless for mathematics since it rejects symbols.
All that we can see of your question is "Is a b a b for all ... " which cannot be answered sensibly. I could try to guess what you might have wanted to ask but I am not sure I'd guess correctly. And in that case, I may as well simply make up my own questions and answer them!

What are rational numbers and how are they used?
A rational number is a number that can be written in the form a/b, where "a" and "b" are integers and b is not equal to zero. For example, whole numbers are rational numbers.
Some rational numbers can be irrational numbers?
No, rational number are ones that can be written as a/b where a and b are integers. Irrational numbers are those real number that are NOT rational.
What are rational nos?
Rational numbers are numbers that can be expressed as a ratio of two integers, a/b, where b is not zero.
Can irritational numbers be integers?
No. All integers are rational numbers with no fractional part-that is, they can be written as A/B such that B goes into A evenly.
Are all negative rational numbers integers?
No, they are not because fractions can be negative also. fractions aren't integers

No. All integers are rational numbers with no fractional part-that is, they can be written as A/B such that B goes into A evenly.
The sum of two rational numbers is a rational number?
Always true. (Never forget that whole numbers are rational numbers too - use a denominator of 1 yielding an improper fraction of the form of all rational numbers namely a/b.)
What numbers r rational?
All those numbers than can b represented as one integer over another integer r rational.
How can you define the set of rational numbers using set notation?
Z=Integers; Rational numbers={a/b| a,b∈Z, b ≠ 0}.
Is the number 88 a rational number?
Yes, the number 88 is rational. A "rational number" is any number that can be expressed as a ratio of integers. That is A/B where A and B are integers, and not zero. Rational numbers include all positive and negative integers and all positive and negative fractions (and mixed numbers when expressed as a fraction).
Can any fraction made up of two whole numbers be rational?
In mathematics, a rational number is any number that can be expressed as the quotient or fraction a/b of two integers, with the denominator b not equal to zero. Since all whole numbers are integers, all fractions made up of whole numbers will be rational.
Are all rational numbers whole numbers?
All rational numbers are not whole numbers, as rational numbers can include fractions.
Number of rational numbers can be found between two distinct rational numbers and b?
There are countably infinite (aleph-null) rational numbers between any two rational numbers.
How many rational numbers are there between a and b?
There are countably infinite rational numbers between any two numbers.
Can you add two irrational numbers to get an rational number?
NoA rational number is a one that can be written as a fraction i.e a/b. where a and be are integers (whole numbers)Considera/b and c/d. Where a b c and d are integers and as such rational numbersa/b + c/d = (ad + bd)/cdad, bd and cd will all be integers and as such a/b + c/d will always be rational
