Question

State true or false, Zero is a rational number
A) True
B) False

Answer 1

In order to solve this question we need to know about whole numbers and integers.
Whole numbers include all natural numbers including zero but it does not include a mixed fraction or decimal number.
Integers include all natural numbers, both positive and negative but not fraction.
Finally we get the required answer.

Complete step-by-step answer:
It is given that the number is a rational number.
Here the definition of the Rational numbers, are those numbers which are integers can be expressed in fraction or in the form of $\dfrac{p}{q}$ where $p$ and $q$ are integers but $q \ne 0$.
As zero comes under the whole number and integers.
So zero is regarded as a rational number because it can be expressed in fraction.
For example, we have to take a number as we can write it as,
$\dfrac{0}{5} = 0$.
The above example shows that the result of that fraction gives zero.
So we can surely say that zero is a rational number.
Therefore, the given statement Zero is a rational number is true.

Thus the correct option is A which is true.

Note: Rational numbers are those numbers which can be expressed in fraction or decimal.
For example $0.75,\dfrac{1}{2}$ etc.
Whole numbers include all sets of natural numbers including zero.
It is considered as whole because it cannot be a mixed fraction or decimal or a rational number.
Zero is both a number and the numerical digit used to represent that number in numerical values.
Today it is difficult to imagine how you could have mathematics without zero.
