Solution - Adding, subtracting and finding the least common multiple

Step  1  :

               1   
 Simplify   ———————
            1000000

Equation at the end of step  1  :

     1       
  ——————— -  100
  1000000    

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  1000000  as the denominator :

           100     100 • 1000000
    100 =  ———  =  —————————————
            1         1000000   

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:

 1 - (100 • 1000000)     -99999999
 ———————————————————  =  —————————
       1000000            1000000 

Final result :

  -99999999              
  ————————— = -100.00000 
   1000000
