Interpret the model to determine the fraction used to divide 1/3.
a. 1/12
b. 1/4
c. 4/3
d. 3/4
the model has 12 squares with 4 shaded but one is shaded with lines.
Based on the information provided, we can interpret the model as representing a fraction division problem.
The model has 12 squares, which represents the whole (1 whole) in this context. Out of these 12 squares, 4 squares are shaded.
To determine the fraction that is being used to divide 1/3, we need to find the fraction that represents the number of shaded squares divided by the total number of squares.
Out of the 4 shaded squares, only 3 are solidly shaded (as one square is shaded with lines). This means that there are 3 shaded squares out of 12 total squares, giving us the fraction 3/12.
Therefore, the fraction used to divide 1/3 is 3/12.
The answer is (a) 1/12.
