Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "3.12" was replaced by "(312/100)".

Step  1  :

            78
 Simplify   ——
            25

Equation at the end of step  1  :

        78
  85 -  ——
        25

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  25  as the denominator :

           85     85 • 25
     85 =  ——  =  ———————
           1        25   

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:

 85 • 25 - (78)     2047
 ——————————————  =  ————
       25            25 

Final result :

  2047            
  ———— = 81.88000 
   25
