In which number does the digit 2 have ten times the value as the underlined digit in the number above?
A 7,429
B 25,381
C 382
D 12,783


To solve this problem, we need to find a number where the digit "2" has ten times the value of the underlined digit in the number above. Let's analyze each option.

### Option A: 7,429
The digit 2 is in the tens place, meaning it represents \( 2 \times 10 = 20 \).
The underlined digit is 9, which is in the ones place, and its value is 9.

Clearly, \( 20 \neq 10 \times 9 \). So, option A is not correct.

### Option B: 25,381
The digit 2 is in the ten thousands place, meaning it represents \( 2 \times 10,000 = 20,000 \).
The underlined digit is 5, which is in the thousands place, and its value is \( 5 \times 1,000 = 5,000 \).

Clearly, \( 20,000 = 10 \times 5,000 \), so option B is correct.

### Option C: 382
The digit 2 is in the ones place, meaning it represents \( 2 \times 1 = 2 \).
The underlined digit is 8, which is in the tens place, and its value is \( 8 \times 10 = 80 \).

Clearly, \( 2 \neq 10 \times 80 \). So, option C is not correct.

### Option D: 12,783
The digit 2 is in the thousands place, meaning it represents \( 2 \times 1,000 = 2,000 \).
The underlined digit is 7, which is in the hundreds place, and its value is \( 7 \times 100 = 700 \).

Clearly, \( 2,000 \neq 10 \times 700 \). So, option D is not correct.

### Conclusion:
The correct answer is **B: 25,381**.

2. How do you determine place value in a number?
3. How is the value of a digit affected by its place?
4. What are other examples where a digit is ten times the value of another digit?
5. What is the place value of a digit in a decimal number?

**Tip:** When dealing with place value, the value of a digit depends on its position in the number. Each place to the left increases its value by a factor of 10.
