A rational number is any number that can be expressed as a whole number, a fraction, or as a nonrepeating decimal. Otherwise, it is an irrational number.
√4/9: When you simplify this, it becomes 2/3. Hence, this is a <em>rational number.</em> √2/24: The simplest form when you reduce is 1/√12. Hence, this is an <em>irrational number</em>. √100: This is equal to 10. Therefore, this is a <em>rational number</em>. 5/4: Since 5/4 is a fraction, it is a <em>rational number</em>. 7.3: This is a fixed decimal, hence, this is<em> rational</em>. 0.002475: This is a fixed decimal, hence, this is <em>rational</em>. 0.01: This is a fixed decimal, hence, this is <em>rational</em>. It is actually equal to 1/10.
