Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "78.5" was replaced by "(785/10)".

Step  1  :

            157
 Simplify   ———
             2 

Equation at the end of step  1  :

  157    
  ——— -  20
   2     

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  2  as the denominator :

          20     20 • 2
    20 =  ——  =  ——————
          1        2   

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:

 157 - (20 • 2)     117
 ——————————————  =  ———
       2             2 

Final result :

  117            
  ——— = 58.50000
