Solution - Reducing fractions to their lowest terms

Step  1  :

             7
 Simplify   ——
            12

Equation at the end of step  1  :

   7    
  —— -  5
  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 :

         5     5 • 12
    5 =  —  =  ——————
         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:

 7 - (5 • 12)     -53
 ————————————  =  ———
      12          12 

Final result :

  -53            
  ——— = -4.41667 
  12
