Step-by-step solution

5 steps
  1. Understand the multiplication model.

    The model represents the multiplication of 41 by the sum of 200 and 5. This can be written as 41×(200+5)41 \times (200 + 5).
    Using the distributive property, this expands to (41×200)+(41×5)(41 \times 200) + (41 \times 5).

  2. Calculate the products shown in the model.

    The first part is 41×20041 \times 200.

    41×200=820041 \times 200 = 8200

    The second part is 41×541 \times 5.

    41×5=20541 \times 5 = 205
  3. Calculate the total product.

    The total product is the sum of the parts:

    8200+205=84058200 + 205 = 8405

    So, the overall multiplication represented by the model is 41×205=840541 \times 205 = 8405.

  4. Identify all possible division equations derived from the model.

    From the partial products:

    • From 41×200=820041 \times 200 = 8200, we can derive: 8200÷200=418200 \div 200 = 41 8200÷41=2008200 \div 41 = 200
    • From 41×5=20541 \times 5 = 205, we can derive: 205÷5=41205 \div 5 = 41 205÷41=5205 \div 41 = 5

    From the total product:

    • From 41×205=840541 \times 205 = 8405, we can derive: 8405÷205=418405 \div 205 = 41 8405÷41=2058405 \div 41 = 205
  5. Compare the derived equations with the given options.

    Let's check each option:

    • 8,200÷200=418,200 \div 200 = 41: This is derived from 41×200=820041 \times 200 = 8200. Correct.
    • 205÷5=41205 \div 5 = 41: This is derived from 41×5=20541 \times 5 = 205. Correct.
    • 8,200÷41=2008,200 \div 41 = 200: This is derived from 41×200=820041 \times 200 = 8200. Correct.
    • 8,405÷205=418,405 \div 205 = 41: This is derived from 41×205=840541 \times 205 = 8405. Correct.
    • 8,405÷41=2058,405 \div 41 = 205: This is derived from 41×205=840541 \times 205 = 8405. Correct.
    • 205÷41=5205 \div 41 = 5: This is derived from 41×5=20541 \times 5 = 205. Correct.

    All the listed equations can be represented by the model.

    The correct answers are:

    • 8,200÷200=41\boxed{8,200 \div 200 = 41}
    • 205÷5=41\boxed{205 \div 5 = 41}
    • 8,200÷41=200\boxed{8,200 \div 41 = 200}
    • 8,405÷205=41\boxed{8,405 \div 205 = 41}
    • 8,405÷41=205\boxed{8,405 \div 41 = 205}
    • 205÷41=5\boxed{205 \div 41 = 5}
