The place value of a digit in a number denotes the value of the location that the digit holds within the number. To find the place value of an underlined digit, you need to consider the position of the digit within the number and its corresponding place value.
**Here’s How to Find the Place Value of the Underlined Digit:**
1. **Identify the Position:** Look at the digit that is underlined and determine its position within the number. For example, in the number 456, if the digit 5 is underlined, it is in the tens place.
2. **Determine the Place Value:** Once you have identified the position of the underlined digit, determine its place value based on its position. In the number 456, the place value of the digit 5 in the tens place is 50.
3. **Consider the Base of the Number System:** In a decimal number system, the place values are powers of 10. The rightmost digit is in the ones place, the next digit to the left is in the tens place, then hundreds, thousands, and so on.
4. **Use Exponents:** To find the place value of a digit, you can represent the number using exponents. For example, in the number 456, the digit 5 in the tens place can be represented as 5 x 10¹.
5. **Practice with Examples:** To become proficient in finding the place value of underlined digits, practice with different numbers and underlined digits. This will help you strengthen your understanding of place value concepts.
6. **Check Your Answer:** After determining the place value of the underlined digit, double-check your answer by verifying it against the position of the digit within the number.
7. **Understand the Relationship:** Recognize the relationship between the position of a digit in a number and its place value. This understanding will help you quickly find the place value of underlined digits.
8. **Visualize the Number:** Visualize the number with the underlined digit in its position to better comprehend its place value within the number.
9. **Apply the Multiplication Rule:** Remember that the place value of a digit is calculated by multiplying the digit by the base of the number system raised to the power of its position.
10. **Use Place Value Charts:** Utilize place value charts or grids to represent numbers and their corresponding place values. This visual aid can enhance your understanding of place value concepts.
11. **Look for Patterns:** Notice any patterns or recurring themes when finding the place value of underlined digits. This can help simplify the process and make it more intuitive.
12. **Break Down Complex Numbers:** For larger numbers with multiple digits, break down the number into its individual place values to easily determine the value of underlined digits.
