Rrational number:
- Rational number is a number of the form a/b, where a and b are integers, and b is not equal to zero.
- We denote the set of rational numbers by "Q".
- As the name suggest Rational numbers are made of Ratio's.
Examples:
5/7, 96/5, 2635/56, ..... are examples of rational numbers.
59/0, 96/0, 89/0, .... are not rational numbers, because the denominator is zero.
- Every whole number is a rational number, because any whole number can be written as a fraction. For example, 3 can be written in the form of fraction p/q as 3/1.
- A rational number is any integer, any fraction, any mixed number, or any decimal, whether positive, negative, or 0.
Examples of rational numbers:
- 1 can be written in the form of fraction p/q as 1/1
- −6 can be written in the form of fraction p/q as -6/1
- 3½ can be written in the form of fraction p/q as 7/2
- −2 can be written in the form of fraction p/q as -2/1
- 0 can be written in the form of fraction p/q as 0/1
- 7.3/8609 is in the form of fraction.
- -1.25 can be written in the form of fraction p/q as -5/4
-
.5 can be written in the form of fraction p/q as 1/2
- 0.007 terminating decimal can be written in the form of fraction p/q as 7/1000
- 0.66666.......repeating decimal can be written in the form of fraction as 2/3.
