Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "3.221" was replaced by "(3221/1000)".

Step  1  :

            3221
 Simplify   ————
            1000

Equation at the end of step  1  :

        3221
  16 -  ————
        1000

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  1000  as the denominator :

           16     16 • 1000
     16 =  ——  =  —————————
           1        1000   

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:

 16 • 1000 - (3221)     12779
 ——————————————————  =  —————
        1000            1000 

Final result :

  12779            
  ————— = 12.77900 
  1000
