To determine the quotient of 3,419 and 11 using an area model, we can break down 3,419 into parts that are easier to divide by 11.

  1. We can break down 3,419 into 3,000 + 400 + 19.
  2. Then, we can divide each part by 11 separately.

Let's proceed with the equations:

  1. Breaking down 3,419:

\[ 3,419 = 3,000 + 400 + 19 \]

So, we express it as:

\[ 3,419 ÷ 11 = (3,000 ÷ 11) + (400 ÷ 11) + (19 ÷ 11) \]

  1. Calculating each part:
  • \( 3,000 ÷ 11 \approx 272.72 \)
  • \( 400 ÷ 11 \approx 36.36 \)
  • \( 19 ÷ 11 \approx 1.73 \)

To simplify, we may round off values for practical use:

  • \( 3,000 ÷ 11 = 272\)
  • \( 400 ÷ 11 = 36\)
  • \( 19 ÷ 11 = 1\)
  1. Now we can finish the equations:

Combining these, we get:

\[ 3,419 ÷ 11 = 272 + 36 + 1 \]

Finally:

\[ 3,419 ÷ 11 = 309 \]

  1. Combining everything together:

  2. First equation completed:

\[ 3,419 ÷ 11 = (3,000 ÷ 11) + (400 ÷ 11) + (19 ÷ 11) \]

  1. Filling in the direct calculations:

\[ 3,419 ÷ 11 = 272 + 36 + 1 \]

  1. The final quotient:

\[ 3,419 ÷ 11 = 309 \]

Putting it all together into the boxes, here is the final result:

  1. \( 3,000 \)
  2. \( 400 \)
  3. \( 19 \)
  4. \( 272 \)
  5. \( 36 \)
  6. \( 1 \)
  7. \( 309 \)

So:

  • 3,419 ÷ 11 = (3,000 ÷ 11) + (400 ÷ 11) + (19 ÷ 11)
  • 3,419 ÷ 11 = 272 + 36 + 1
  • 3,419 ÷ 11 = 309
