Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "421.25" was replaced by "(42125/100)".

Step  1  :

            1685
 Simplify   ————
             4  

Equation at the end of step  1  :

         1685
  506 -  ————
          4  

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  4  as the denominator :

            506     506 • 4
     506 =  ———  =  ———————
             1         4   

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:

 506 • 4 - (1685)     339
 ————————————————  =  ———
        4              4 

Final result :

  339            
  ——— = 84.75000 
   4
