Solution - Reducing fractions to their lowest terms

Step  1  :

             1 
 Simplify   ———
            128

Equation at the end of step  1  :

        1 
  1 -  ———
       128

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  128  as the denominator :

          1     1 • 128
     1 =  —  =  ———————
          1       128  

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:

 128 - (1)     127
 —————————  =  ———
    128        128

Final result :

  127           
  ——— = 0.99219 
  128
