Question

Every rational number is:

• A. a natural number
• B. an integer
• C. a real number
• D. a whole number

Answer 1

The correct option is C

a real number

Rational number:

A rational number is a number that can be represented in the form of $\frac{p}{q}$ where $p\&q$ are integers and $q$ is not equal to 0.

Example: $\frac{1}{2},-\frac{3}{4}\mathrm{and}\frac{3}{10}$

Rational and irrational numbers taken together are known as real numbers.

Example: $3,0,1.5\mathrm{and}\sqrt{5}$

Therefore, every real number is either a rational number or an irrational number.

Therefore, every rational number is a real number. Hence, option C is correct.
