No No Children. It is denoted by letter Q
Sir, can we know the reason?
Sir, 1/2
Sure, before that, can someone give me an example of a rational number?
Sir, 5
Perfect!The rational numbers given by you, are 1/2 and 5/1 as the integer 5 can also be represented as 5/1.Since any rational number can be represented as a Quotient of p/q where p and q are integers, q non-zero, Q letter is used to represent the set of all rational numbers.
