Question

is zero a rattional number?can you write it in the form p/q‚where p and q are intigers and q 0

Answer 1

Yes 0 is a rational number as it can be written in the form of p/q where p and q are integers and q never equals to 0 as shown below :
$0 = \frac{0}{1} \: where \: 0 \: and \: 1 \\ are \: integers.$
These following types of numbers are always rational:
1. Natural numbers
2.Whole numbers
3.Integers
Also in any fraction p/q, q will never be equal to 0 and if it is then the number can't be defined as a number or called to be an undefined number.
