Interpret the model to determine the fraction used to divide 1/3 .

To interpret the model, imagine a number line divided into equal parts. The model states that we need to divide 1/3 by a certain fraction.

For example, if the model indicates dividing by 2, it means we divide 1/3 into two equal parts. In this case, each part would be 1/6 of the whole.

Similarly, if the model indicates dividing by 4, it means we divide 1/3 into four equal parts. In this case, each part would be 1/12 of the whole.

So, the fraction used to divide 1/3 is represented by the model and can vary depending on the specific division shown.
