Answer 1

Integers are positive and negative whole numbers including zero, such as {-3, -2, -1, 0, 1, 2, 3}.

When these whole numbers are written in the form of ratio of whole numbers it is known as rational numbers. So, rational numbers can be positive, negative or zero. So, a rational number can be expressed in the form of p/q where ‘p’ and ‘q’ are integers and ‘q’ is not equal to zero.
