 Simplify   ———
            125

Equation at the end of step  1  :

         6      27
  (1 -  ——) -  ———
        10     125

Step  2  :

            3
 Simplify   —
            5

Equation at the end of step  2  :

        3      27
  (1 -  —) -  ———
        5     125

Step  3  :

Rewriting the whole as an Equivalent Fraction :

 3.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  5  as the denominator :

          1     1 • 5
     1 =  —  =  —————
          1       5  

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 :

 3.2       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 - (3)     2
 ———————  =  —
    5        5

Equation at the end of step  3  :

  2     27
  — -  ———
  5    125

Step  4  :

Calculating the Least Common Multiple :

 4.1    Find the Least Common Multiple

      The left denominator is :       5 

      The right denominator is :       125 

      Least Common Multiple:
      125 

Calculating Multipliers :

 4.2    Calculate multipliers for the two fractions


    Denote the Least Common Multiple by  L.C.M 
    Denote the Left Multiplier by  Left_M 
    Denote the Right Multiplier by  Right_M 
    Denote the Left Deniminator by  L_Deno 
    Denote the Right Multiplier by  R_Deno 

   Left_M = L.C.M / L_Deno = 25

   Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

 4.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)²   and  (y²+y)/(y+1)³  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

   L. Mult. • L. Num.      2 • 25
   ——————————————————  =   ——————
         L.C.M              125  

   R. Mult. • R. Num.       27
   ——————————————————  =   ———
         L.C.M             125

Adding fractions that have a common denominator :

 4.4       Adding up the two equivalent fractions

 2 • 25 - (27)      23
 —————————————  =  ———
      125          125

Final result :

   23           
  ——— = 0.18400 
  125
