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
Are whole numbers a rational number?
Yes. A rational number is one that you can write as a fraction a/b, with integers a and b (b not equal to zero). For a whole number, set b = 1. For example, 5 = 5/1, so it is a rational number.

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.
Why are venn diagrams used?
A.(Integers) (Rational numbers)B.(Rational numbers) (Integers)C.(Integers) (Rational numbers)D.(Rational numbers) (Real numbers)
Is 3.1415926531 rational?
Numbers in the form of a/b, where a and b are integers, are called rational numbers. 3.1415926531 can be written as 31415926531/10000000000. So it is a rational number.
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).
