Fractions

Write a command line program in the language of your choice that will take operations on fractions as an input and produce a fractional result.

Legal operators shall be *, /, +, - (multiply, divide, add, subtract) Operands and operators shall be separated by one or more spaces Mixed numbers will be represented by whole_numerator/denominator. e.g. "3_1/4" Improper fractions and whole numbers are also allowed as operands Example run:

? 1/2 * 3_3/4

= 1_7/8

? 2_3/8 + 9/8

= 3_1/2

Assumptions:

  1. Input is valid in the form of Infix operation
  2. Fractions are valid
  3. Invalid input will throw error
