Integers — MATHS STD 7 — Question

A rational number is a number that can be represented $\frac{\text{a}}{\text{b}}$ 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 $\frac{\text{a}}{\text{b}}$ with $b$ not equal to zero so it is a rational number. In the given options, option $D$ is irrational number. option $B$ and $C$ are not lying between $-3$ and $3.$ Only option A lies $-3$ and $3$ and is a rational number.
