Ming placed a zero in the number 590 because the digit 9 in 59 has a value of 90. When multiplying, especially when aligning numbers, it's important to recognize the place value of digits to ensure accurate calculations. Therefore, the correct response would be:

The digit 9 in 59 has a value of 90.

wrong

I apologize for the misunderstanding. Let’s reconsider the question in detail.

In a multiplication problem where Ming is working with the number 590, the zero is likely placed because he was consolidating the product based on place value. If he was multiplying, it may indicate that he understood the significance of the zero when considering the tens or hundreds position in the multiplication process.

The correct explanation for placing a zero might relate to how multiplication is structured when dealing with multi-digit numbers, and it's commonly linked with the distributive property of multiplication over addition.

Based on your response options, the most plausible explanation is "She thought that 1 × 9 equaled zero." if the context of multiplication was misunderstood that led to an incorrect computation step.

It appears there might be some missing details in your question, but I can help explain the division of 432 by 12.

To solve \(432 \div 12\):

  1. Determine how many times 12 goes into 43 (the first two digits of 432).
    • 12 goes into 43 three times (since \(12 \times 3 = 36\)).
  2. Subtract 36 from 43 which leaves you with 7.
  3. Bring down the next digit (which is 2) to make it 72.
  4. Now determine how many times 12 goes into 72.
    • 12 goes into 72 exactly six times (since \(12 \times 6 = 72\)).
  5. Subtract 72 from 72 which results in 0.

So, the complete division gives \(432 \div 12 = 36\).

Therefore, the first error would likely refer to how many times 12 was counted in 43, where the correct answer should state that 12 goes into 43 three times, leading to the overall correct answer of 36.

Please check the problem and make sure to align your understanding with this calculation! If there are specific options or more context, feel free to provide them for a more tailored response.

what step

To clarify the steps and identify where the first error occurs in the division of \( 432 \div 12 \), here’s a breakdown of the process:

  1. Set Up the Division: Divide 432 by 12.

  2. First Digit: Look at how many times 12 can go into the first part of the dividend, which is 43.

    • Error May Occur Here: If the student said that 12 goes into 43 five times, that would be incorrect because \(12 \times 5 = 60\), which is too high. The correct statement is that 12 goes into 43 three times (since \(12 \times 3 = 36\)).

  3. Subtract: Once you’ve correctly figured out that 12 goes into 43 three times:

    • Subtract \(36\) from \(43\) to get \(7\).

  4. Bring Down the Next Digit: Bring down the next digit from 432 (which is 2) to make it 72.

  5. Second Part of Division: Determine how many times 12 goes into 72.

    • Here, 12 goes into 72 exactly six times (because \(12 \times 6 = 72\)).

  6. Final Result: When you have no remainder after subtracting, the answer is \(36\).

Summary of the First Error

So, the first error appears in Step 2: determining how many times 12 goes into 43. The correct answer is 3 times, leading to a final answer of 36 for the entire division problem.

If the student mistakenly said that 12 goes into 43 a different number of times, that step was where the initial error occurred.

you sure

Let me clarify to ensure the explanation is accurate and complete:

When dividing \(432 \div 12\), the process goes as follows:

  1. Determine how many times 12 goes into 43:

    • The first digits to consider are 43 from 432.
    • Correct Calculation: 12 goes into 43 three times (since \(12 \times 3 = 36\)).
    • Mistake: If a student states that 12 goes into 43 four times (because \(12 \times 4 = 48\) which exceeds 43), that would be incorrect.

  2. Subtract: After multiplying, you would subtract:\(43 - 36 = 7\).

  3. Bring down the next digit: Bring down the 2 from 432, resulting in 72.

  4. Determine how many times 12 goes into 72:

    • 12 goes into 72 exactly six times (since \(12 \times 6 = 72\)).
    • Subtract: \(72 - 72 = 0\).

  5. Final Answer: Therefore, the final result of \(432 \div 12\) is \(36\).

Summary of the Error

The first error occurs at Step 1:

  • If the student incorrectly stated that 12 goes into 43 a number greater than 3 (for example, 4), that would be wrong.

Question Silvio completed this addition problem. Why did Silvio place a number above the 1 in 142? NOTE: There is a check answer button in the bottom right corner.

In the given addition problem, Silvio placed a number above the 1 in 142 as part of a regrouping process during the addition.

The correct response is:

The sum of 4 tens and 9 tens is 13 tens, which is regrouped as 1 hundred and 3 tens.

Explanation:

When adding numbers that involve carrying (or regrouping), if you have 4 tens (which is 40) and 9 tens (which is 90), the total is 13 tens (130). In this case:

  • You write down 3 in the tens place but have to carry over the 1 to the hundreds place, which is why Silvio placed a number above the 1 in 142.

This process effectively means that he's accounting for the redistribution of value from the tens column to the hundreds column.
