Interpret the model to determine the fraction used to divide 3/8.

10/16 3/4 5/8 1/2

To interpret the model, we need to determine which fraction from the given options is used to divide 3/8.

Let's consider each option:

10/16: This fraction is larger than 3/8, so dividing 3/8 by 10/16 would result in a smaller value. This option is not correct.

3/4: This fraction is greater than 3/8, so dividing 3/8 by 3/4 would give a smaller value. This option is not correct.

5/8: This fraction is equal to 3/8, so dividing 3/8 by 5/8 would result in a value of 1. This option is correct.

1/2: This fraction is smaller than 3/8, so dividing 3/8 by 1/2 would give a larger value. This option is not correct.

Therefore, the correct fraction to divide 3/8 is 5/8.
