Let’s go step by step to find the value of each underlined digit.
Remember: In a 3-digit number, the places are:
-
Hundreds (leftmost digit) → multiply by 100
-
Tens (middle digit) → multiply by 10
-
Ones (rightmost digit) → multiply by 1
We look at which place the underlined digit is in, then write its value.

First row (already done as examples):
- 154 → 5 is underlined → tens place → 5 × 10 =
50
- 447 → 7 is underlined → ones place → 7 × 1 =
7
- 843 → 8 is underlined → hundreds place → 8 × 100 =
800
Now let’s do the rest:
Second row:
- 345 → 5 is underlined → ones → 5 × 1 =
5
- 894 → 9 is underlined → tens → 9 × 10 =
90
- 334 → 3 (first one) is underlined → hundreds → 3 × 100 =
300
Third row:
- 674 → 7 is underlined → tens → 7 × 10 =
70
- 253 → 5 is underlined → tens → 5 × 10 =
50
- 446 → 4 (first one) is underlined → hundreds → 4 × 100 =
400
Fourth row:
- 451 → 1 is underlined → ones → 1 × 1 =
1
- 376 → 7 is underlined → tens → 7 × 10 =
70
- 625 → 6 is underlined → hundreds → 6 × 100 =
600
Fifth row:
- 855 → 5 (middle) is underlined → tens → 5 × 10 =
50
- 542 → 4 is underlined → tens → 4 × 10 =
40
- 168 → 6 is underlined → tens → 6 × 10 =
60
Sixth row:
- 369 → 3 is underlined → hundreds → 3 × 100 =
300
- 164 → 6 is underlined → tens → 6 × 10 =
60
- 738 → 3 is underlined → tens → 3 × 10 =
30
Seventh row:
- 409 → 4 is underlined → hundreds → 4 × 100 =
400
- 389 → 9 is underlined → ones → 9 × 1 =
9
- 799 → 9 (middle) is underlined → tens → 9 × 10 =
90
Eighth row:
- 707 → 0 is underlined → tens → 0 × 10 =
0
- 328 → 2 is underlined → tens → 2 × 10 =
20
- 848 → 4 is underlined → tens → 4 × 10 =
40

Final Answer:
5, 90, 300
70, 50, 400
1, 70, 600
50, 40, 60
300, 60, 30
400, 9, 90
0, 20, 40
