Let’s solve each part step by step.
---
I) Give the expanded form of the following numbers:
We break each number into hundreds, tens, and ones.
a) 192
→ 1 hundred + 9 tens + 2 ones
✔ Correct: 100 + 90 + 2 = 192
b) 170
→ 1 hundred + 7 tens + 0 ones
✔ Correct: 100 + 70 + 0 = 170
c) 105
→ 1 hundred + 0 tens + 5 ones
✔ Correct: 100 + 0 + 5 = 105

II) Fill in the blanks:
We add up the given parts to get the full number.
a) 1 hundred + 3 tens + 0 ones
→ 100 + 30 + 0 =
130
b) 1 hundred + 0 tens + 7 ones
→ 100 + 0 + 7 =
107
c) 8 tens + 1 one
→ 80 + 1 =
81
d) 100 + 50 + 4
→ 100 + 50 = 150; 150 + 4 =
154
e) 100 + 90 + 0
→ 100 + 90 =
190
---
III) Give the expanded form of the following numbers:
Break them down like before.
a) 168 → already done: 100 + 60 + 8
✔
b) 120
→ 100 + 20 + 0
So:
100 + 20 + 0
c) 109
→ 100 + 0 + 9
So:
100 + 0 + 9
*(Note: Sometimes we skip writing “+ 0”, but since the example for 168 included all three parts, we’ll include zero here too.)*

IV) Give the place value of the underlined number:
Place value means what digit is worth based on its position (hundreds, tens, or ones).
a) 89 — assuming the
8 is underlined → it’s in the tens place →
80
b) 200 — assuming the
2 is underlined → it’s in the hundreds place →
200
c) 157 — assuming the
7 is underlined → it’s in the ones place →
7
d) 106 — assuming the
6 is underlined → it’s in the ones place →
6
*(Note: Since the original image doesn’t show which digit is underlined, we assume standard practice: usually the rightmost digit is underlined in such problems unless specified. But looking at common patterns:*
- In 89, if 8 is underlined → tens → 80
- In 200, if 2 is underlined → hundreds → 200
- In 157, if 7 is underlined → ones → 7
- In 106, if 6 is underlined → ones → 6
This matches typical worksheet design.)
