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!
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.
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.
No, they are not because fractions can be negative also. fractions aren't integers
Rational numbers are numbers that can be expressed as a ratio of two integers, a/b, where b is not zero.
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.
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.

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.)
All those numbers than can b represented as one integer over another integer r rational.
To determine if ( b^2(c + d) ) is rational, we need to know the values of ( b ), ( c ), and ( d ). If ( b ), ( c ), and ( d ) are all rational numbers, then ( b^2 ) is rational (since the square of a rational number is rational) and ( c + d ) is also rational (as the sum of two rational numbers is rational). Therefore, the product ( b^2(c + d) ) would be rational as well. However, if any of these values are irrational, then ( b^2(c + d) ) may not be 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.
Z=Integers; Rational numbers={a/b| a,b∈Z, b ≠ 0}.
