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

1 answer

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.
