Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "9.79" was replaced by "(979/100)".

Step  1  :

            979
 Simplify   ———
            100

Equation at the end of step  1  :

        979
  20 -  ———
        100

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  100  as the denominator :

           20     20 • 100
     20 =  ——  =  ————————
           1        100   

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:

 20 • 100 - (979)     1021
 ————————————————  =  ————
       100            100 

Final result :

  1021            
  ———— = 10.21000 
  100
