Question

The following question has two parts. First, answer part A Then, answer part B

Use mental math to answer the question

Part A
Carter wants to use the model above to solve 273 divide by 13. Explain how he would find parts A, B, and C of the model


Part B
The final quotient for 273 divide by 13 is _______

Answer 1

### Part A

To solve \(273 \div 13\) using a model, Carter can break down the division process into parts:

1. **Part A: Estimate how many times 13 fits into the first digit (or digits) of 273.**
- Look at the first two digits, 27.
- Determine how many times 13 fits into 27.
- Since \(13 \times 2 = 26\) (which is close to 27), Carter would find that 13 fits into 27 about 2 times.

2. **Part B: Subtract and bring down the next digit.**
- Subtract \(26\) (which is \(13 \times 2\)) from \(27\), which leaves \(1\).
- Now bring down the next digit, which is \(3\), making it \(13\).

3. **Part C: Finally, find how many times 13 fits into 13.**
- Since \(13 \times 1 = 13\), Carter finds that 13 fits into 13 exactly 1 time.
- Now, combine the two parts together: \(2\) from the earlier step and \(1\) from this step, giving a total quotient of \(21\).

### Part B

The final quotient for \(273 \div 13\) is **21**.
