Solution - Reducing fractions to their lowest terms

Step  1  :

             7
 Simplify   ——
            12

Equation at the end of step  1  :

        7
  1 -  ——
       12

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

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

          1     1 • 12
     1 =  —  =  ——————
          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:

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

Final result :

   5           
  —— = 0.41667 
  12
