Aaj hum aapko Rational numbers ki defination with examples ke saath batane waale hai?
Rational and irrational numbers se related , aapk bahut adhik questions aa rahe hai.
Un sabhi questions ko ek-ek kark reply karne me mujhe time adhik lag jaata hai . Jissey aapko , aapk question ka reply late se milta hai.
Isliye maine socha ki iss topic par aapko detail me bata du aur isse related question bhi aapko solve karna shikha du. Taki aapko iss topic se koi bhi problem naa ho. To isiliye mai aaj iss topic ke baare me bataunga.

Ab mai isska defination batata hu.

Defination of Rational number

Unn sabhi number ko hum Rational number kahte hai  jise hum P/Q ke form me likh sakte hai , jaha par P and Q dono  integer hai lekin , Q ki value zero  nahi ho.

Generally , Rational number ko hum nimntam (lowest) term me likhte hai . lowest term kahne ka matalab , 4/6 ko hum lowest term me 2/3 likhte hai.
Isi prakar 12/18 ko 2/3, 44/55 ko 4/5 etc . lowest terms me likhte hai.
Lowest term me likhane k karan , Rational number me P and Q , integer k saath-saath prime numbers bhi hote hai.

Example-:  2/3 , 1/2 , -3/7 , 6/(-5) , -9/-5  etc are rational numbers.

Means, ye huaa ki rational numbers   ko hum fraction ya ratio ke form me likh sakte hai but denominator (Niche wala number) zero nhi hona chahiye.

Aayiye ab iska kuch example dekhate hai.

Example of Rational number

1. Sabhi Natural numbers , Rational numbers hote hai

Ex-: Hum ek natural number 2  lete hai , jise hum 2/1 likh sakte hai . Isliye 2 ek rational number bhi hai.

2. Sabhi whole numbers, natural numbers hote hai.

Ex-:  5 ek whole number hai . Jise hum 5/1 likh sakte hai. Isliye 5 rational number hai.
