Answer 1

To determine which student, Brianna or Gavin, correctly calculated the quotient of 552 divided by 23 using partial quotients, let's break down their calculations step by step.

Brianna's Work:

1. Step one: Subtract \(20 \times 23\) from 552.

   • \(20 \times 23 = 460\)
   • \(552 - 460 = 92\)

2. Step two: Subtract \(4 \times 23\) from 92.

   • \(4 \times 23 = 92\)
   • \(92 - 92 = 0\)

3. Add the partial quotients:

   • Brianna's partial quotients: \(20 + 4 = 24\)

So, Brianna concludes that \(552 / 23 = 24\).

Gavin's Work:

1. Step one: Subtract \(10 \times 23\) from 552.

   • \(10 \times 23 = 230\)
   • \(552 - 230 = 322\)

2. Step two: Subtract \(10 \times 23\) from 322.

   • \(10 \times 23 = 230\)
   • \(322 - 230 = 92\)

3. Step three: Subtract \(2 \times 23\) from 92.

   • \(2 \times 23 = 46\)
   • \(92 - 46 = 46\)

4. Step four: Subtract \(2 \times 23\) from 46.

   • \(2 \times 23 = 46\)
   • \(46 - 46 = 0\)

5. Add the partial quotients:

   • Gavin's partial quotients: \(10 + 10 + 2 + 2 = 24\)

So, Gavin also concludes that \(552 / 23 = 24\).

---

Conclusion: Both Brianna and Gavin arrived at the same final quotient of 24, which is correct. Therefore, both students correctly calculated the quotient using the partial quotient method.

The answer to \(552 / 23\) is indeed 24.
