Solution - Adding, subtracting and finding the least common multiple

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "0.00000672" was replaced by "(00000672/100000000)".

Step  1  :

               21  
 Simplify   ———————
            3125000

Equation at the end of step  1  :

          21  
  1 +  ———————
       3125000

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  3125000  as the denominator :

          1     1 • 3125000
     1 =  —  =  ———————————
          1       3125000  

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:

 3125000 + 21     3125021
 ————————————  =  ———————
   3125000        3125000

Final result :

  3125021           
  ——————— = 1.00001 
  3125000
