Step  1  :

             9 
 Simplify   ———
            500

Equation at the end of step  1  :

         148      9 
  (20 -  ———) -  ———
         10      500

Step  2  :

            74
 Simplify   ——
            5 

Equation at the end of step  2  :

         74      9 
  (20 -  ——) -  ———
         5      500

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 :

           20     20 • 5
     20 =  ——  =  ——————
           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:

 20 • 5 - (74)     26
 —————————————  =  ——
       5           5 

Equation at the end of step  3  :

  26     9 
  —— -  ———
  5     500

Step  4  :

Calculating the Least Common Multiple :

 4.1    Find the Least Common Multiple

      The left denominator is :       5 

      The right denominator is :       500 

      Least Common Multiple:
      500 

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 = 100

   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.      26 • 100
   ——————————————————  =   ————————
         L.C.M               500   

   R. Mult. • R. Num.       9 
   ——————————————————  =   ———
         L.C.M             500

Adding fractions that have a common denominator :

 4.4       Adding up the two equivalent fractions

 26 • 100 - (9)     2591
 ——————————————  =  ————
      500           500 

Final result :

  2591           
  ———— = 5.18200 
  500
