Answer

The rational numbers from the list are: - \(0.11\overline{1}\) - \(\frac{0}{-10}\) - \(\frac{2}{-2}\) - \(\sqrt{36}\)

Solution

To determine which of the provided numbers are rational, let's evaluate each one: 1. **\(\frac{-5}{0}\)**: Division by zero is undefined, so this is **not** a rational number. 2. **\(\frac{0}{0}\)**: This is an indeterminate form and is **not** a rational number. 3. **\(0.11\overline{1}\)**: - This represents a repeating decimal: \(0.1111\ldots\), which can be expressed as the fraction \(\frac{1}{9}\). - Since it can be written as a ratio of two integers, it **is** a rational number. 4. **\(\frac{0}{-10}\)**: - This simplifies to \(0\). - Zero is a rational number because it can be expressed as \(\frac{0}{1}\). 5. **\(\sqrt{2}\)**: - \(\sqrt{2}\) is an irrational number, meaning it cannot be expressed as a ratio of two integers. 6. **\(\frac{2}{-2}\)**: - This simplifies to \(-1\). - Since \(-1\) is an integer, it **is** a rational number. 7. **\(\sqrt{36}\)**: - \(\sqrt{36} = 6\), which is an integer. - Integers are rational numbers because they can be expressed as a ratio (e.g., \(\frac{6}{1}\)). **Rational Numbers from the List:** - \(0.11\overline{1}\) - \(\frac{0}{-10}\) - \(\frac{2}{-2}\) - \(\sqrt{36}\) **Answer:** All of the following are rational:  \(0.11 \overline{1}\),  \(\frac{0}{-10}\),  \(\frac{2}{-2}\), and  \(\sqrt{36}\).

The Deep Dive

Let’s break this down! Rational numbers are numbers that can be expressed as the quotient of two integers (where the denominator is not zero). - \( \frac{-5}{0} \) and \( \frac{0}{0} \) are both not rational because division by zero is undefined. - \( 0.11 \overline{1} \) can be expressed as a fraction, making it rational. - \( \frac{0}{-10} \) equals \( 0 \), which is also rational (since \( 0 \) can be expressed as \( \frac{0}{1} \)). - \( \sqrt{2} \) is an irrational number because it cannot be expressed as a fraction of integers. - \( \frac{2}{-2} \) simplifies to \(-1\), which is rational. - \( \sqrt{36} = 6\), another rational number. So, the rational numbers from the list are: \( 0.11 \overline{1} \), \( 0 \) (from \( \frac{0}{-10} \)), \( -1 \) (from \( \frac{2}{-2} \)), and \( 6 \) (from \( \sqrt{36} \)).
