Solution - Reducing fractions to their lowest terms

Step  1  :

             5
 Simplify   ——
            12

Equation at the end of step  1  :

   5    
  —— -  180
  12    

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  12  as the denominator :

           180     180 • 12
    180 =  ———  =  ————————
            1         12   

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:

 5 - (180 • 12)     -2155
 ——————————————  =  —————
       12            12  

Final result :

  -2155              
  ————— = -179.58333 
   12
