Question

which division problem is shown by the model

0.66 divide by 3 = 0.22

0.66 divide by 3 = 0.26

0.78 divide by 3 = 0.62

0.78 divide by 3 = 0.26

Answer 1

The division problems represented by the model contain some inaccuracies in the calculations, particularly with respect to the division of 0.66 and 0.78 by 3.

Let's clarify the division problems:

1. \(0.66 \div 3 = 0.22\) **(Correct: \(0.66 \div 3 = 0.22\))**
2. \(0.66 \div 3 = 0.26\) **(Incorrect)**
3. \(0.78 \div 3 = 0.62\) **(Incorrect)**
4. \(0.78 \div 3 = 0.26\) **(Correct: \(0.78 \div 3 = 0.26\))**

So, the correct division problems based on accurate calculations should be:
- \(0.66 \div 3 = 0.22\)
- \(0.78 \div 3 = 0.26\)

The two incorrect statements are likely errors if they were intended to show correct division results.

If we were to summarize the correct operations based on the valid calculations:
- The correct interpretation of the model indicates valid results for the divisions \(0.66 \div 3\) and \(0.78 \div 3\), with outputs of \(0.22\) and \(0.26\), respectively.
