Remove dependency to Fractions

[Rekkonnect]

Only one file requires the usage of Fractions and the implementation relies on it without a clear purpose; the numeric computations can all be worked out easily without relying on fractions. Not to mention other unreasonable usages of BigInteger. The file that uses this package is this. Additionally, the package is explicitly referenced in two other projects without a real usage.

This is a leaking package reference that serves no purpose in most applications, and opinionates the usage of a library that has poor performance for real-life implementations using numeric fractions. Minimizing package references is very helpful for consumers to reduce build times and package cache sizes.

agree with minimizing dependencies
could you please send pr to remove it, i believe there are still many math related operations need it
