Underlined Digits worksheet for math practice.

I can see the second section of the worksheet asks to "Underline the correct digit in each number given its value." I need to examine each number and underline the digit that corresponds to the given value.

Let me go through each row:

First row:
- 13 with value 10: The 1 in 13 represents 10 (tens place), so I should underline the 1.
- 55 with value 50: The first 5 in 55 represents 50 (tens place), so I should underline the first 5.
- 15 with value 5: The 5 in 15 represents 5 (ones place), so I should underline the 5.
- 62 with value 60: The 6 in 62 represents 60 (tens place), so I should underline the 6.

Second row:
- 87 with value 7: The 7 in 87 represents 7 (ones place), so I should underline the 7.
- 40 with value 40: The 4 in 40 represents 40 (tens place), so I should underline the 4.
- 47 with value 40: The 4 in 47 represents 40 (tens place), so I should underline the 4.
- 14 with value 4: The 4 in 14 represents 4 (ones place), so I should underline the 4.

Third row:
- 59 with value 50: The 5 in 59 represents 50 (tens place), so I should underline the 5.
- 75 with value 5: The 5 in 75 represents 5 (ones place), so I should underline the 5.
- 66 with value 60: The first 6 in 66 represents 60 (tens place), so I should underline the first 6.
- 30 with value 0: The 0 in 30 represents 0 (ones place), so I should underline the 0.

Fourth row:
- 28 with value 8: The 8 in 28 represents 8 (ones place), so I should underline the 8.
- 53 with value 3: The 3 in 53 represents 3 (ones place), so I should underline the 3.
- 11 with value 1: The second 1 in 11 represents 1 (ones place), so I should underline the second 1.
- 16 with value 10: The 1 in 16 represents 10 (tens place), so I should underline the 1.

Fifth row:
- 24 with value 20: The 2 in 24 represents 20 (tens place), so I should underline the 2.
- 99 with value 9: The second 9 in 99 represents 9 (ones place), so I should underline the second 9.
- 90 with value 90: The 9 in 90 represents 90 (tens place), so I should underline the 9.
- 90 with value 90: The 9 in 90 represents 90 (tens place), so I should underline the 9.

I've now solved both parts of the worksheet. Let me summarize the complete solution.

The completed worksheet would look like this:

Part 1: Write the value of the underlined digits
- 23: 20, 98: 90, 87: 80, 65: 60
- 22: 20, 91: 90, 53: 50, 51: 50
- 85: 80, 10: 10, 11: 10, 33: 30
- 15: 10, 32: 30, 98: 90, 42: 40
- 25: 20, 83: 80, 36: 30, 19: 10

Part 2: Underline the correct digit in each number given its value
- 13 (underline 1), 55 (underline first 5), 15 (underline 5), 62 (underline 6)
- 87 (underline 7), 40 (underline 4), 47 (underline 4), 14 (underline 4)
- 59 (underline 5), 75 (underline 5), 66 (underline first 6), 30 (underline 0)
- 28 (underline 8), 53 (underline 3), 11 (underline second 1), 16 (underline 1)
- 24 (underline 2), 99 (underline second 9), 90 (underline 9), 90 (underline 9)

This completes the task of solving the worksheet on understanding place value.
