1. Is zero a rational number?Can you write it in the form p/q,where p and q are integers and \(q \ne 0\).

Yes, we may rewrite 0 as 0/1 , 0/2 , 0/3 (where 0 and 1,2,3 are integers and q=1,2,3 which is not equal to zero).

Because we know that a number is called as rational number if it can be expressed in p/q form.
