Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "33.15" was replaced by "(3315/100)".

Step  1  :

            663
 Simplify   ———
            20 

Equation at the end of step  1  :

         663
  221 -  ———
         20 

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  20  as the denominator :

            221     221 • 20
     221 =  ———  =  ————————
             1         20   

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:

 221 • 20 - (663)     3757
 ————————————————  =  ————
        20             20 

Final result :

  3757             
  ———— = 187.85000 
   20
