Question

Difference is a rational number. give reasons​

Answer 1

Answer:

A rational number is a number that can be in the form pq where p and q are integers and q is not equal to zero. ... So let b = 0 and 'a' is a rational number then we get a + 0 = a, hence zero satisfies this property.

Answer 2

Answer:

A rational number is a number that can be in the form pq where p and q are integers and q is not equal to zero. Zero satisfies the above definition. ... Let b = 0 and then we get a+(0+c)=(a+0)+c , hence both are equal so zero satisfies this property also. And from this we can say that zero is a rational number.
