From the developer:
FractionCalc will perform standard operations on fractions, improper fractions, or mixed numbers. The solutions are returned in either fractional form or decimal. The user can perform a single operation or can enter a series of operations by checking the "Multiple Operations" check box. There is also a decimal-to-fraction and fraction-to-decimal converter.
