Solution - Adding, subtracting and finding the least common multiple

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "86.00001" was replaced by "(8600001/100000)".

Step  1  :

            8600001
 Simplify   ———————
            100000 

Equation at the end of step  1  :

  8600001    
  ——————— +  4
  100000     

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  100000  as the denominator :

         4     4 • 100000
    4 =  —  =  ——————————
         1       100000  

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:

 8600001 + 4 • 100000     9000001
 ————————————————————  =  ———————
        100000            100000 

Final result :

  9000001            
  ——————— = 90.00001 
  100000
