Solution - Adding, subtracting and finding the least common multiple

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "900.9005" was replaced by "(9009005/10000)".

Step  1  :

            1801801
 Simplify   ———————
             2000  

Equation at the end of step  1  :

  1801801    
  ——————— -  1
   2000      

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  2000  as the denominator :

         1     1 • 2000
    1 =  —  =  ————————
         1       2000  

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:

 1801801 - (2000)     1799801
 ————————————————  =  ———————
       2000            2000  

Final result :

  1799801             
  ——————— = 899.90050 
   2000
