Solution - Reducing fractions to their lowest terms

Step  1  :

            20
 Simplify   ——
            9 

Equation at the end of step  1  :

        20     
  (0 -  ——) -  4
        9      

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  9  as the denominator :

         4     4 • 9
    4 =  —  =  —————
         1       9  

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 - (4 • 9)     -56
 —————————————  =  ———
       9            9 

Final result :

  -56            
  ——— = -6.22222 
   9
