Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "87.3" was replaced by "(873/10)".

Step  1  :

            873
 Simplify   ———
            10 

Equation at the end of step  1  :

         873
  128 -  ———
         10 

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  10  as the denominator :

            128     128 • 10
     128 =  ———  =  ————————
             1         10   

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:

 128 • 10 - (873)     407
 ————————————————  =  ———
        10            10 

Final result :

  407            
  ——— = 40.70000 
  10
