Solution - Adding, subtracting and finding the least common multiple

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "197.8333" was replaced by "(1978333/10000)".

Step  1  :

            1978333
 Simplify   ———————
             10000 

Equation at the end of step  1  :

         1978333
  218 -  ———————
          10000 

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  10000  as the denominator :

            218     218 • 10000
     218 =  ———  =  ———————————
             1         10000   

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

 2.2       Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

 218 • 10000 - (1978333)     201667
 ———————————————————————  =  ——————
          10000              10000 

Final result :

  201667            
  —————— = 20.16670 
  10000
