Write a procedure
to read a rational number given in the form “numerator”/“denominator”, and store these two values in num and den, respectively. Additionally, you must remove all common factors from num and den. For instance, if the input has
66/12
the values after the call must be num = 11 and den = 2.
Precondition
1 ≤ num ≤ 109 and 1 ≤ den ≤ 109
Observation You only need to submit the required procedure; your main program will be ignored.
