Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "7.9" was replaced by "(79/10)".

Step  1  :

            79
 Simplify   ——
            10

Equation at the end of step  1  :

         79
  520 -  ——
         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 :

            520     520 • 10
     520 =  ———  =  ————————
             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:

 520 • 10 - (79)     5121
 ———————————————  =  ————
       10             10 

Final result :

  5121             
  ———— = 512.10000 
   10
