Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "7.85" was replaced by "(785/100)".

Step  1  :

            157
 Simplify   ———
            20 

Equation at the end of step  1  :

  157    
  ——— +  5
  20     

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Adding a whole to a fraction

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

         5     5 • 20
    5 =  —  =  ——————
         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:

 157 + 5 • 20     257
 ————————————  =  ———
      20          20 

Final result :

  257            
  ——— = 12.85000 
  20
