Rational Numbers

We have observed that in the set of natural numbers

The set

The set

is called the set of rational number, and we ask the readers to note that the divisions by

The fundamental compositions defined in

For convenience, by

**N**, there was no additive identity so it was extended to a set**W**, the set of whole numbers which we defined as**W = {0, 1, 2, 3, …. }**and then we thought of the operation of subtractor, and found that the subtraction was not unrestrictedly possible in the system of whole and, therefore, W was extended to the set of integers**I**. We now draw our attention towards the operation of division and observe that**15/3 = 5**has a meaning in**I**whereas**15/4**is an undefined term in**I**. So to**I**we now attach new elements so as to obtain another family, to be denoted by**Q**, and call it the set of rational numbers.The set

**Q**of rational numbersThe set

**Q = {p/q | p, q****I and q ≠ 0}**is called the set of rational number, and we ask the readers to note that the divisions by

**0**is not permissible and**I ⊂ Q**.The fundamental compositions defined in

**Q**are also addition and multiplication. We shall now state the properties of addition and multiplication and order relation in**Q**.For convenience, by

**m**in**Q**we shall understand an element of the form**p/q; p, q I, q ≠ 0**etc.**Services: -**Rational Numbers Homework | Rational Numbers Homework Help | Rational Numbers Homework Help Services | Live Rational Numbers Homework Help | Rational Numbers Homework Tutors | Online Rational Numbers Homework Help | Rational Numbers Tutors | Online Rational Numbers Tutors | Rational Numbers Homework Services | Rational NumbersSubmit Your Query ???
