Rational Numbers

Rational numbers are those numbers which can be represented in the form of
p/q where p and q are real numbers and q cannot be zero. We generally use “q”
to represent rational numbers in mathematical world.

They can be represented in two ways- either in fraction or in decimal forms and
contain the set of integers. If a/b and b/c are two rational numbers then the two
rational numbers are equal only if ac=bd.

Performing any operation using rational numbers is just like using fractions.
Some important points on rational numbers:

1. All the rational numbers are subset of real numbers or we can say all rational
numbers lie in real line.

2. Countless rational numbers lie between two rational numbers.

3. There can be infinite numbers of rational numbers between two integers.

4. Any integer can be represented as rational number.

5. Rational numbers are countable numbers as we can easily count them.
Rational numbers are very densely populated as I mentioned above that there
can be infinite rational number between two integers.

We can also find many rational numbers between two numbers. We can
perform many operations on rational numbers like addition, subtraction, division
and multiplication.

The Rational numbers are those numbers which can either be whole numbers
or fractions or decimals. Rational numbers can be written as a ratio of two
integers in the form 'p/q' where 'p' and 'q' are integers and 'q' is nonzero.

A rational number is simply a ratio of two integers, for example1/5 is a rational
number (1 divided by 5, or the ratio of 1 to 5). A set of rational numbers is
denoted by capital Q.

The rational numbers are contrasted with irrational numbers such like Pi, square
roots and logarithms of numbers. The rational numbers are a subset of the real
numbers.

In mathematics, a number is Rational if, it can written in a form p/q where p and
q are integers, q is not equal to zero.

The decimal numbers can be written in that form: for example 0.77 is 77/100,
4.40938 = 440938/100000 etc.

A rational number is p/q where q is nonzero.

Examples:p/q= 1/1=1

p/q= 22/100=0.22

p/q=3/1000=0.003

p/q=9/0="q" can't be zero(q≠0).
