Final answer:
Without the model for reference, it's unclear which fraction is being asked about. However, by comparing the given options, 2/4 (which simplifies to 1/2) is the smallest fraction among the options listed.The correct option is D.
Step-by-step explanation:
To compare fractions and identify which fraction is less than another, particularly the fraction represented by the model, we need to understand the value of each option. Unfortunately, the question does not provide the model that we are supposed to compare the options with, hence we cannot determine which fraction is less without that context. However, by understanding fractions, we can compare the given options among themselves by considering the numerators and denominators.
For instance, when comparing fractions with the same denominator such as 11/16 and 13/16, we can see that 11/16 is less than 13/16 since it has a smaller numerator. When comparing 3/4 to 2/4, we can see that 3/4 is greater as it has a larger numerator. Also, 3/4 is the same as 12/16 when the denominator is equalized, thus 3/4 would be greater than 11/16 and 13/16.
To accurately answer which fraction is less than the model, we would need the representation of that model. However, between the options provided, 2/4, which simplifies to 1/2, is the smallest fraction listed if we exclude any external reference point provided by the model.
