Math worksheet focusing on expanded form and place value for numbers up to 200.

Let’s go step by step through each part of the worksheet. We’ll solve every question carefully so you understand how to do it yourself next time.

---

I) Give the expanded form of the following numbers:

Expanded form means breaking a number into hundreds, tens, and ones.

a) 192
→ 1 hundred (that’s 100)
→ 9 tens (that’s 90)
→ 2 ones (that’s 2)
So: 100 + 90 + 2

But the worksheet asks for words:
→ 1 hundred + 9 tens + 2 ones

b) 170
→ 1 hundred = 100
→ 7 tens = 70
→ 0 ones = 0
So: 1 hundred + 7 tens + 0 ones

c) 105
→ 1 hundred = 100
→ 0 tens = 0
→ 5 ones = 5
So: 1 hundred + 0 tens + 5 ones

---

II) Fill in the blanks:

This is the reverse — we’re given parts and need to add them up.

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
= 150 + 4 = 154

e) 100 + 90 + 0
= 190 + 0 = 190

---

III) Give the expanded form of the following numbers:

Same as Part I, but now write the actual values (like 100, 60, 8).

a) 168 → already done: 100 + 60 + 8

b) 120
→ 100 + 20 + 0 → but usually we don’t write +0 if it’s at the end. But since the format shows three blanks, let’s include it:
100 + 20 + 0

Wait — looking at example (a), they wrote “100 + 60 + 8” — no zeros omitted. So for consistency:

Actually, 120 = 100 + 20 + 0? Hmm… but sometimes teachers accept 100 + 20. Let’s check the pattern.

In part (a): 168 = 100 + 60 + 8 → all digits shown.

So for 120: hundreds digit = 1 → 100, tens digit = 2 → 20, ones digit = 0 → 0.

So: 100 + 20 + 0

But wait — maybe they expect just non-zero parts? Let’s see part c: 109.

109 = 100 + 0 + 9? Or 100 + 9?

Looking back at Part I(c): 105 was written as “1 hundred + 0 tens + 5 ones” — so zero is included.

So yes, include zero places.

Thus:

b) 120 = 100 + 20 + 0

c) 109 = 100 + 0 + 9

---

IV) Give the place value of the underlined number:

Place value means what that digit is worth based on its position.

a) 89 → underline is on 9 → it’s in the ones place → so place value = 9

b) 200 → underline is on 2 → it’s in the hundreds place → so place value = 200

c) 167 → underline is on 7 → ones place → 7

d) 106 → underline is on 0 → it’s in the tens place → so even though it’s zero, its place value is 0 (because 0 tens = 0)

Wait — place value of the digit 0 in 106: it’s in the tens place, so its value is 0 × 10 = 0.

Yes, so answer is 0

---

Now let’s double-check everything before writing final answers.

✔ Part I:
a) 192 → 1, 9, 2 ✔️
b) 170 → 1, 7, 0 ✔️
c) 105 → 1, 0, 5 ✔️

✔ Part II:
a) 100+30+0=130 ✔️
b) 100+0+7=107 ✔️
c) 80+1=81 ✔️
d) 100+50+4=154 ✔️
e) 100+90+0=190 ✔️

✔ Part III:
a) 168 = 100+60+8 ✔️
b) 120 = 100+20+0 ✔️
c) 109 = 100+0+9 ✔️

✔ Part IV:
a) 9 in 89 → ones → 9 ✔️
b) 2 in 200 → hundreds → 200 ✔️
c) 7 in 167 → ones → 7 ✔️
d) 0 in 106 → tens → 0 ✔️

All correct!
