Solution - Adding, subtracting and finding the least common multiple

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "20.00065" was replaced by "(2000065/100000)".

Step  1  :

            400013
 Simplify   ——————
            20000 

Equation at the end of step  1  :

        400013
  50 -  ——————
        20000 

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  20000  as the denominator :

           50     50 • 20000
     50 =  ——  =  ——————————
           1        20000   

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:

 50 • 20000 - (400013)     599987
 —————————————————————  =  ——————
         20000             20000 

Final result :

  599987            
  —————— = 29.99935 
  20000
