🔷 What is Expanded Form?
The
expanded form of a number shows the value of each digit based on its place (hundreds, tens, ones). For example:
> 125 = 100 + 20 + 5
> → 1 hundred, 2 tens, 5 ones
We'll apply this to each number.

✔ Now, let’s write the expanded form for each:
#### a. 125
Already given:
100 + 20 + 5
---
#### b. 364
- 3 hundreds = 300
- 6 tens = 60
- 4 ones = 4
→
300 + 60 + 4
---
#### c. 471
- 4 hundreds = 400
- 7 tens = 70
- 1 one = 1
→
400 + 70 + 1
---
#### d. 521
- 5 hundreds = 500
- 2 tens = 20
- 1 one = 1
→
500 + 20 + 1
---
#### e. 412
- 4 hundreds = 400
- 1 ten = 10
- 2 ones = 2
→
400 + 10 + 2
---
#### f. 523
- 5 hundreds = 500
- 2 tens = 20
- 3 ones = 3
→
500 + 20 + 3
---
#### g. 214
- 2 hundreds = 200
- 1 ten = 10
- 4 ones = 4
→
200 + 10 + 4
---
#### h. 162
- 1 hundred = 100
- 6 tens = 60
- 2 ones = 2
→
100 + 60 + 2
---
#### i. 322
- 3 hundreds = 300
- 2 tens = 20
- 2 ones = 2
→
300 + 20 + 2
---
#### j. 524
- 5 hundreds = 500
- 2 tens = 20
- 4 ones = 4
→
500 + 20 + 4
---
#### k. 478
- 4 hundreds = 400
- 7 tens = 70
- 8 ones = 8
→
400 + 70 + 8
---
#### l. 854
- 8 hundreds = 800
- 5 tens = 50
- 4 ones = 4
→
800 + 50 + 4
---
#### m. 569
- 5 hundreds = 500
- 6 tens = 60
- 9 ones = 9
→
500 + 60 + 9

📌 Explanation:
To find the expanded form:
1. Identify the digits in
hundreds,
tens, and
ones places.
2. Multiply each digit by its place value:
- Hundreds → ×100
- Tens → ×10
- Ones → ×1
3. Add them together.
For example:
364 → 3×100 = 300, 6×10 = 60, 4×1 = 4 → 300 + 60 + 4
✔ This helps understand how numbers are built using place values!
