Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "642.4" was replaced by "(6424/10)".

Step  1  :

            3212
 Simplify   ————
             5  

Equation at the end of step  1  :

         3212
  871 -  ————
          5  

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  5  as the denominator :

            871     871 • 5
     871 =  ———  =  ———————
             1         5   

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:

 871 • 5 - (3212)     1143
 ————————————————  =  ————
        5              5  

Final result :

  1143             
  ———— = 228.60000
