1. Problem Description

The problem asks whether the number $7.11$ is rational or irrational.

2. Solution Steps

A rational number is a number that can be expressed as a fraction $\frac{p}{q}$, where $p$ and $q$ are integers and $q \neq 0$. An irrational number cannot be expressed in this form.

The given number is $7.11$.

We can write $7.11$ as a fraction by multiplying and dividing by 100:

$7.11 = \frac{7.11 \times 100}{100} = \frac{711}{100}$

Since $711$ and $100$ are both integers, $7.11$ can be written as a fraction of two integers. Therefore, $7.11$ is a rational number.

3. Final Answer

Rational
