How to represent mixed fractions in java

Question

There is a way to represent fractions over here. Is there a clear abstraction to represent mixed fractions, so that you can perform addition, subtraction, multiplication operations on it.

Answer 1

A mixed fraction is only a display difference and not a mathematical one. You can just convert it to mixed when you print the answer.

Answer 2

You could perhaps do this by extending Fraction: you might want to add a new constructor that takes a whole number in addition to the numerator/denominator new MixedFraction(2,3,4) for 2 3/4, and override toString to display in the desired format.
