Here are some operations on fractions: As shown in the examples for multiplication and subtraction, one usually reduces the answer to its simplest form. Thus, 1/24/5=2/5 rather than the 4/10 that results from merely multiplying across. When applying these operations we want to leave the two operands unchanged. For example, given fractions A and B,AB should create a new fraction and not change A or B. Q: Develop an Abstract Data Type for the Fractions.
