Introduction

In mathematics, understanding the value of digits in numbers is crucial for performing various calculations and operations. When a digit is underlined, it can significantly change the value of the number. In this article, we will explore the value of the underlined digit in the number 234,500,450 and choose the best answer from the given options.

Understanding Place Value

Before we dive into the problem, let's understand the concept of place value. Place value refers to the value of a digit in a number based on its position. In the number 234,500,450, each digit has a specific place value:

2 is in the hundred million's place
3 is in the ten million's place
4 is in the million's place
5 is in the hundred thousand's place
0 is in the ten thousand's place
4 is in the thousand's place
5 is in the hundred's place
0 is in the ten's place
0 is in the one's place

The Underlined Digit

Now, let's focus on the underlined digit in the number 234,500,450. Since there is no underlined digit in the given number, we will assume that the underlined digit is the one that is not explicitly mentioned. In this case, we will consider the digit 5 in the hundred thousand's place as the underlined digit.

Analyzing the Options

Now, let's analyze the options given:

A. Hundred thousand B. Ten thousand C. Thousand D. Ones

Option A: Hundred Thousand

The digit 5 is in the hundred thousand's place, which means it represents the value of 500,000. Therefore, the underlined digit is indeed in the hundred thousand's place.

Option B: Ten Thousand

The digit 0 is in the ten thousand's place, which means it represents the value of 0. Therefore, the underlined digit is not in the ten thousand's place.

Option C: Thousand

The digit 4 is in the thousand's place, which means it represents the value of 4,000. Therefore, the underlined digit is not in the thousand's place.

Option D: Ones

The digit 0 is in the one's place, which means it represents the value of 0. Therefore, the underlined digit is not in the one's place.

Conclusion

Based on the analysis of the options, the correct answer is:

A. Hundred thousand

The underlined digit in the number 234,500,450 is indeed in the hundred thousand's place, representing the value of 500,000.

Conclusion

Q: What is the place value of a digit in a number?

A: The place value of a digit in a number is the value it represents based on its position. For example, in the number 234,500,450, the digit 2 is in the hundred million's place, the digit 3 is in the ten million's place, and so on.

Q: How do I determine the place value of a digit in a number?

A: To determine the place value of a digit in a number, you need to look at the position of the digit. The position of the digit is determined by the number of places it is from the right of the number. For example, in the number 234,500,450, the digit 2 is in the fourth place from the right, so it is in the hundred million's place.

Q: What is the difference between a place value and a value?

A: A place value is the value of a digit in a number based on its position, while a value is the actual value of the digit. For example, in the number 234,500,450, the digit 2 has a place value of 200,000,000, but its actual value is 2.

Q: How do I convert a number from one place value to another?

A: To convert a number from one place value to another, you need to multiply or divide the number by the appropriate factor. For example, to convert the number 234,500,450 from the hundred million's place to the ten thousand's place, you would multiply it by 0.00001.

Q: What is the importance of understanding place value?

A: Understanding place value is crucial for performing various calculations and operations. By recognizing the place value of each digit, you can accurately perform calculations and avoid errors.

Q: How do I practice place value?

A: You can practice place value by working with numbers and performing calculations. You can also use online resources and practice exercises to help you improve your understanding of place value.
