A Number is said to be a fraction number if it can be written in the for of a/b in which

the denominator b should not be equal to 0.

Ex: 8/9 is a fraction but 7/0 is not a fraction.

Again, a fraction of two integers is a rational number. It is also a real number.

The irrational numbers are those numbers which cannot be written in form of p/q

where p and q are integers.

Ex: √2, √3, √5, etc. are irrational numbers.
