Solution - Adding, subtracting and finding the least common multiple

Step  1  :

               3   
 Simplify   ———————
            1000000

Equation at the end of step  1  :

          3   
  1 -  ———————
       1000000

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

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

          1     1 • 1000000
     1 =  —  =  ———————————
          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:

 1000000 - (3)      999997
 —————————————  =  ———————
    1000000        1000000

Final result :

   999997           
  ——————— = 1.00000 
  1000000
