Solution - Adding, subtracting and finding the least common multiple

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "12.0012125" was replaced by "(120012125/10000000)".

Step  1  :

            960097
 Simplify   ——————
            80000 

Equation at the end of step  1  :

        960097
  19 -  ——————
        80000 

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  80000  as the denominator :

           19     19 • 80000
     19 =  ——  =  ——————————
           1        80000   

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:

 19 • 80000 - (960097)     559903
 —————————————————————  =  ——————
         80000             80000 

Final result :

  559903           
  —————— = 6.99879 
  80000
