Rational numbers can be written as fractions with an integer as the numerator and a non-zero integer as the denominator that do not share any common factors. Rational numbers can be represented by either terminating or repeating decimals. Between any two rational numbers, there exist two additional rational numbers. Irrational numbers cannot be expressed as a fraction with an integer numerator and denominator. Prime numbers are only divisible by 1 and themselves, while composite numbers are numbers greater than 1 that are not prime numbers.

6. Rational numbers are those numbers
which cannot be written as integers.
They are written as an integer divided by
another integer and the dominator is not
and both numbers do not have
common factors.
Rational numbers have either ending or
non-terminating repeating decimal
expressions.
Between every 2 rational numbers , you
will find 2 more rational numbers.
Rational numbers can be called fractions.

7. All numbers which cannot be written as an integer up
integer where the denominator is zero and both integer
are co prime are irrstional numbers
They are non terminating non repeating decimal expan
The roots of prime number are irrational.

8. Repeating decimals are decimals that contain a infin
Number of digits.
Examples
0.3333…..
1.9…….
7.6868686868……

9. Terminating decimals are decimals that contain a finite
number of digits.
For example
1.36.8
2.0.125
3.4.5

10. A prime number is divisible by only two numbers, itsel
And 1
For example
2,3,5,7,11,13,17,19,23,………

11. A composite is a whole number greater than 1 and is no
a prime number

12. Every composite number can be expressed as a produc
primes and this expression is unique ,apart from the
in which the primes occur.

13. For positive integers a and b, there exist unique intege
q and r satisfying the relation:
a=bq+r

14. Let p be a prime number.
If p divides (a)2 , then p divides a ,
where a is a positive integer.
