The correct Answer is:
To solve the question "The numbers which are not divisible by 2 are called as", we need to analyze the options provided and determine which one correctly identifies these numbers. ### Step-by-Step Solution: 1. **Understand the Definition**: - Numbers that are not divisible by 2 are known as odd numbers. Odd numbers are integers that cannot be evenly divided by 2. 2. **Evaluate the Options**: - **Prime Numbers**: These are numbers greater than 1 that have no positive divisors other than 1 and themselves. While many prime numbers are odd (like 3, 5, 7), the number 2 is a prime number and is even. Therefore, this option is not correct. - **Rational Numbers**: These are numbers that can be expressed as the quotient of two integers (like 1/2, 3/4). Rational numbers can be even or odd, so this option does not fit our criteria. - **Whole Numbers**: Whole numbers include 0, 1, 2, 3, and so on. While some whole numbers are odd, many are even (like 2, 4, 6). Thus, this option is also incorrect. - **Odd Numbers**: These are defined as numbers like 1, 3, 5, 7, etc., which are not divisible by 2. This option correctly identifies the numbers we are looking for. 3. **Conclusion**: - Based on the definitions and evaluations of the options, the correct answer to the question is **Odd Numbers**. ### Final Answer: The numbers which are not divisible by 2 are called **Odd Numbers**. ---
