 Hi and welcome to the session. Let's discuss the following question. It says, is 0 a rational number? Can you write it in the form p by q where p and q are integers and q not equal to 0? Let's now move on to the solution. An answer to the first question is yes, 0 is a rational number because a rational number is of the form p by q where q not equal to 0. And 0 can also be written in this form. That is, 0 is equal to 0 upon 1 or it can be written as 0 upon 2 or it can be written as 0 upon 3 and so on. And we can see that denominators that is q are not equal to 0. So it is a rational number. Hence our answer is yes, 0 is a rational number because it can be written as 0 upon 1 or 0 upon 2 or 0 upon 3 etc. And denominator q can also be taken as negative integer. So this completes the question. Bye for now. Take care. Hope you enjoyed the session.
