Let's solve the
Expanded Form Practice worksheet step by step.
🔹 What is Expanded Form?
Expanded form means writing a number as the sum of the values of each digit. For example:
- 239 = 200 + 30 + 9
We break down each number into hundreds, tens, and ones (or whatever place values are needed).

Now let’s go through each number:
---
1.
82
- 8 is in the tens place → 80
- 2 is in the ones place → 2
- So:
80 + 2
✔ Answer: 80 + 2
---
2.
239
- 2 is in the hundreds place → 200
- 3 is in the tens place → 30
- 9 is in the ones place → 9
- So:
200 + 30 + 9
✔ Answer: 200 + 30 + 9
---
3.
126
- 1 is in the hundreds place → 100
- 2 is in the tens place → 20
- 6 is in the ones place → 6
- So:
100 + 20 + 6
✔ Answer: 100 + 20 + 6
---
4.
17
- 1 is in the tens place → 10
- 7 is in the ones place → 7
- So:
10 + 7
✔ Answer: 10 + 7
---
5.
599
- 5 is in the hundreds place → 500
- 9 is in the tens place → 90
- 9 is in the ones place → 9
- So:
500 + 90 + 9
✔ Answer: 500 + 90 + 9
---
6.
874
- 8 is in the hundreds place → 800
- 7 is in the tens place → 70
- 4 is in the ones place → 4
- So:
800 + 70 + 4
✔ Answer: 800 + 70 + 4
---
7.
940
- 9 is in the hundreds place → 900
- 4 is in the tens place → 40
- 0 is in the ones place → 0
- So:
900 + 40 + 0
(Note: Even though it's zero, we usually write it for completeness unless instructed otherwise.)
✔ Answer: 900 + 40 + 0
---
✔ Final Answers:
| Number | Expanded Form |
|--------|----------------|
| 82 | 80 + 2 |
| 239 | 200 + 30 + 9 |
| 126 | 100 + 20 + 6 |
| 17 | 10 + 7 |
| 599 | 500 + 90 + 9 |
| 874 | 800 + 70 + 4 |

> 💡 Tip: Always check the
place value of each digit — hundreds, tens, ones — and multiply by the appropriate power of ten.
