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.
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.
No, they are not because fractions can be negative also. fractions aren't integers
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}.
