Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "63.71" was replaced by "(6371/100)".

Step  1  :

            6371
 Simplify   ————
            100 

Equation at the end of step  1  :

  6371    
  ———— -  20
  100     

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  100  as the denominator :

          20     20 • 100
    20 =  ——  =  ————————
          1        100   

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:

 6371 - (20 • 100)     4371
 —————————————————  =  ————
        100            100 

Final result :

  4371            
  ———— = 43.71000 
  100
