Solution - Adding, subtracting and finding the least common multiple

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "8.76923" was replaced by "(876923/100000)".

Step  1  :

            876923
 Simplify   ——————
            100000

Equation at the end of step  1  :

        876923
  18 -  ——————
        100000

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

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

           18     18 • 100000
     18 =  ——  =  ———————————
           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:

 18 • 100000 - (876923)     923077
 ——————————————————————  =  ——————
         100000             100000

Final result :

  923077           
  —————— = 9.23077 
  100000
