Question

A rational number between $-3$ and $3$ is :

• A. $0$
• B. $-4.3$
• C. $-3.4$
• D. $\mathrm{1.101100110001.}...$

Answer 1

The correct option is A $0$

A rational number is a number that can be represented $\frac{a}{b}$, where $a$ and $b$ are integers and $b$ is not equal to $0$.

A rational number can also be represented in decimal form and the resulting decimal is a repeating decimal.

Also any decimal number that is repeating can be written in the form $\frac{a}{b}$, with $b$ not equal to zero, so it is a rational number.

In the given options, option $D$ is irrational number,

while options $B$ and $C$ are not lying between $-3$ and $3$.

Only option A lies between $-3$ and $3$ and is a rational number.

So, correct answer is option $A$.
