Solution - Reducing fractions to their lowest terms

Step  1  :

            33
 Simplify   ——
            4 

Equation at the end of step  1  :

        33
  12 -  ——
        4 

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  4  as the denominator :

           12     12 • 4
     12 =  ——  =  ——————
           1        4   

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 • 4 - (33)     15
 —————————————  =  ——
       4           4 

Final result :

  15           
  —— = 3.75000
