Let’s solve each problem step by step using place value understanding. The key is to recognize what each term (ones, tens, hundreds, thousands, etc.) represents numerically and how multiplication or division by powers of 10 affects the place value.

Place Value Reference:
- Ones = 1
- Tens = 10
- Hundreds = 100
- Thousands = 1,000
- Ten-Thousands = 10,000
- Hundred-Thousands = 100,000
- Millions = 1,000,000

1. 10 times 30 thousands is __________.
- 30 thousands = 30 × 1,000 =
30,000
- 10 × 30,000 =
300,000
- 300,000 =
3 hundred-thousands
✔ Answer: 300,000

2. 100 times 7 ones is __________.
- 7 ones = 7
- 100 × 7 =
700
- 700 =
7 hundreds
✔ Answer: 700
---
3. 1000 times 4 hundreds is __________.
- 4 hundreds = 4 × 100 =
400
- 1000 × 400 =
400,000
- 400,000 =
4 hundred-thousands
✔ Answer: 400,000

4. ________ times 9 thousands is 9 millions.
- 9 thousands = 9,000
- 9 millions = 9,000,000
- We need: ? × 9,000 = 9,000,000
→ Divide: 9,000,000 ÷ 9,000 =
1,000
✔ Answer: 1,000
---
5. ________ times 20 thousands is 200 thousands.
- 20 thousands = 20,000
- 200 thousands = 200,000
- ? × 20,000 = 200,000
→ 200,000 ÷ 20,000 =
10
✔ Answer: 10
---
6. 90 thousands divided by 100 is __________.
- 90 thousands = 90,000
- 90,000 ÷ 100 =
900
- 900 =
9 hundreds
✔ Answer: 900
---
7. 5 millions divided by 10 is __________.
- 5 millions = 5,000,000
- 5,000,000 ÷ 10 =
500,000
- 500,000 =
5 hundred-thousands
✔ Answer: 500,000
---
8. 800 thousands divided by ________ is 8 hundreds.
- 800 thousands = 800,000
- 8 hundreds = 800
- So: 800,000 ÷ ? = 800
→ ? = 800,000 ÷ 800 =
1,000
✔ Answer: 1,000
---
9. 3 hundreds divided by 10 is __________.
- 3 hundreds = 300
- 300 ÷ 10 =
30
- 30 =
3 tens
✔ Answer: 30
---
10. 7 thousands divided by 1,000 is __________.
- 7 thousands = 7,000
- 7,000 ÷ 1,000 =
7
- 7 =
7 ones
✔ Answer: 7
