>>separate the sublist in the nested list
  iterate over the nested list
>>separate elementes in the sublist
  iterate over the sublist
>>for each sublist, calculate the fraction
  set the first element to the numerator 
  set the second element is the denominator
  store the result to a variable called:total
>>return the variable total

def sum_fractions(nested_list:list):  
    total = 0  
    list_of_sum = list()  
    for sublist in nested_list:  
        division = int(sublist[0]) / int(sublist [1])  
        total += division  
    return round(total)
