Question

is zero a rational number ? justify​

Answer 1

The numbers which can be written as p/q where p and q, both are integers and p is not equal to 0 are called rational numbers. when we know that 0 can be written as 0/1 with denominator 1, we see that both 0 and 1 are integers, where 1 is not equal to 0. so we conclude that 0 is a rational mumber an not irrational.

Answer 2

The numbers of the form $\frac{a}{b}$ where A and B are integers and b is not equal to zero are called rational number .

Yes zero is a rational number as it can be written as $\frac{0}{1}$,$\frac{0}{2}$,$\frac{0}{-5}$ etc.
