Compare two proper or improper fractions. Adjust the numerators and denominators of the two fractions using sliders, and see circle or rectangle area models as well as the equivalent decimal and percent values (values may be rounded). The area models, fraction, decimal, and percent can be hidden individually using check boxes. Possible numerator values are 0 to 20. Possible denominator values are 1 to 20. The area models are restricted to values less than or equal to 10.
