The correct Answer is:
To determine whether the statement "The product of three odd numbers is odd" is true or false, we can analyze the properties of odd numbers and perform a step-by-step verification. ### Step-by-Step Solution: 1. **Understanding Odd Numbers**: - An odd number is defined as any integer that cannot be evenly divided by 2. This means when you divide an odd number by 2, there is always a remainder of 1. - Examples of odd numbers include 1, 3, 5, 7, 9, etc. **Hint**: Remember that odd numbers have a specific property related to division by 2. 2. **Multiplying Odd Numbers**: - Let's take three odd numbers. For example, we can use 3, 5, and 7. - The product of these numbers can be calculated as follows: - First, multiply the first two odd numbers: \[ 3 \times 5 = 15 \] - Now, multiply the result by the third odd number: \[ 15 \times 7 = 105 \] **Hint**: When multiplying, keep track of the results step by step. 3. **Analyzing the Result**: - The result of multiplying 3, 5, and 7 is 105, which is also an odd number. - This pattern holds true for any three odd numbers. 4. **Generalizing the Result**: - If we take any odd number \(a\), \(b\), and \(c\), we can express them in the form \(2n + 1\) where \(n\) is an integer. - The product can be represented as: \[ (2n_1 + 1)(2n_2 + 1)(2n_3 + 1) \] - When you expand this product, you will find that it results in an odd number. 5. **Conclusion**: - Since the product of any three odd numbers results in another odd number, we can conclude that the statement "The product of three odd numbers is odd" is true. ### Final Answer: The statement is **True**.
