2. Key Information: We need to reach the number 200,060. The number can be decomposed as parts of powers of ten.
3. Potential Approaches: Break down the number 200,060 according to the place values in the decimal system: hundreds of thousands, thousands, hundreds, tens, and ones.
4. Key Formulas: None required, just understanding of place value decomposition in the decimal system.
5. Appropriate Approach: Decompose 200,060 by identifying the parts they represent in terms of powers of ten.
6. Steps:
- Start by identifying the highest place value in the number (hundreds of thousands).
- Decompose into hundreds of thousands, then consider lower place values to complete the number.
7. Assumptions: None necessary beyond basic decimal structure understanding.
8. Complex Parts: Considering the separate components (parts of powers of ten) that add to 200,060.
9. Edge Cases: Not applicable.
10. Instructions: Analyze the correctness of given multiple-choice options.
11. Compare choices to determine which accurately adds up to 200,060.
12. Common Mistakes: Misidentifying place values, errors in addition.
13. Changes: Different values would directly change their respective impact on the addition to 200,060.
Let's solve this problem step by step:
- Step 1: Identify the highest place value found in 200,060, which is hundreds of thousands.
- Step 2: The number 200,060 can be broken down as follows:
- It has 2 in the hundred thousand place, representing 2×100,000.
- The tens place has 6, representing 6×10.
- There are no thousands, hundreds, or ones to account for in the construction of 200,060.
- Step 3: Check the calculations:
- 2×100,000=200,000
- 6×10=60
- Add these results together: 200,000+60=200,060
- Step 4: Evaluate the choices provided:
- Choice 1 represents 1×100,000+2×10,000+6×10=120,060, which is incorrect.
- Choice 2 represents 2×10,000+6×1,000=26,000, which is incorrect.
- Choice 3 represents 2×100,000+6×10=200,060, which is correct.
- Choice 4 represents 2×100,000+6×100=200,600, which is incorrect.
Therefore, the decomposition exercise that correctly reaches the number 200,060 is:
2×100,000+6×10=200,060
2×100,000+6×10=200,060
