Problem Description:
The task is to determine the
place value of the underlined digit in each number provided. Place value refers to the value of a digit based on its position in a number. For example, in the number 234:
- The digit "2" is in the hundreds place, so its place value is 200.
- The digit "3" is in the tens place, so its place value is 30.
- The digit "4" is in the ones place, so its place value is 4.
Solution Approach:
1. Identify the position of the underlined digit in each number.
2. Determine the place value of that digit based on its position (ones, tens, hundreds, etc.).
3. Write the place value as the answer.
Step-by-Step Solution:
#### 1. \( \underline{4} \)
- The digit "4" is in the

#### 2. \( 6\underline{9} \)
- The digit "9" is in the
ones place.
- Place value: \( 9 \)
#### 3. \( \underline{7}9 \)
- The digit "7" is in the
tens place.
- Place value: \( 70 \)
#### 4. \( \underline{6} \)
- The digit "6" is in the
ones place.
- Place value: \( 6 \)
#### 5. \( \underline{8}1 \)
- The digit "8" is in the
tens place.
- Place value: \( 80 \)
#### 6. \( \underline{3} \)
- The digit "3" is in the
ones place.
- Place value: \( 3 \)
#### 7. \( \underline{7} \)
- The digit "7" is in the
ones place.
- Place value: \( 7 \)
#### 8. \( 6\underline{0} \)
- The digit "0" is in the
ones place.
- Place value: \( 0 \)
#### 9. \( \underline{5} \)
- The digit "5" is in the
ones place.
- Place value: \( 5 \)
#### 10. \( \underline{8} \)
- The digit "8" is in the
ones place.
- Place value: \( 8 \)
#### 11. \( \underline{4}0 \)
- The digit "4" is in the
tens place.
- Place value: \( 40 \)
#### 12. \( 3\underline{8} \)
- The digit "8" is in the
ones place.
- Place value: \( 8 \)
#### 13. \( \underline{7}2 \)
- The digit "7" is in the
tens place.
- Place value: \( 70 \)
#### 14. \( 6\underline{4} \)
- The digit "4" is in the
ones place.
- Place value: \( 4 \)
#### 15. \( \underline{6}1 \)
- The digit "6" is in the
tens place.
- Place value: \( 60 \)
#### 16. \( 9\underline{1} \)
- The digit "1" is in the
ones place.
- Place value: \( 1 \)
