Every rational number is
a. a natural number
b. an integer
c. a real number
d. a whole number

Solution:

A number is called a rational number, if it can be written in the form p/q, where p and q are integers and q ≠ 0.

Any fraction with non zero denominators is a rational number

Example - 1/3, 1/5, 1/7, 3/4, ……

All rational numbers and all irrational numbers together make the collection of real numbers

So every real number is either rational or irrational

Therefore, every rational number is a real number.

✦ Try This: What are rational numbers?

A rational number is a number that is of the form p/q where p and q are integers and q is not equal to 0.

The set of rational numbers is denoted by Q.

In other words, If a number can be expressed as a fraction where both the numerator and the denominator are integers, the number is a rational number.

Example: 1/2, -3/4, 3/10, -7/10, 14/99…..

Therefore, the rational number is a number that is of the form p/q where p and q are integers and q is not equal to 0.
