Step  1  :

             9 
 Simplify   ———
            100

Equation at the end of step  1  :

    15     15      9 
  (——— +  ———) +  ———
   100    100     100

Step  2  :

             3
 Simplify   ——
            20

    15     3      9 
  (——— +  ——) +  ———
   100    20     100

Step  3  :

             3

            20

Equation at the end of step  3  :

    3     3      9 
  (—— +  ——) +  ———
   20    20     100

Step  4  :

Adding fractions which have a common denominator :

 4.1       Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

 3 + 3      3
 —————  =  ——
  20       10

Equation at the end of step  4  :

   3     9 
  —— +  ———
  10    100

Step  5  :

Calculating the Least Common Multiple :

 5.1    Find the Least Common Multiple

      The left denominator is :       10 

      The right denominator is :       100 

      Least Common Multiple:
      100 

Calculating Multipliers :

 5.2    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 = 10

   Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

 5.3      Rewrite the two fractions into equivalent fractions

   L. Mult. • L. Num.      3 • 10
   ——————————————————  =   ——————
         L.C.M              100  

   R. Mult. • R. Num.       9 
   ——————————————————  =   ———
         L.C.M             100

Adding fractions that have a common denominator :

 5.4       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:

 3 • 10 + 9      39
 ——————————  =  ———
    100         100

Final result :

   39           
  ——— = 0.39000 
  100
