Solution - Adding, subtracting and finding the least common multiple

Step  1  :

             9 
 Simplify   ———
            100

Equation at the end of step  1  :

    4     2      9 
  (—— +  ——) +  ———
   25    50     100

Step  2  :

             1
 Simplify   ——
            25

Equation at the end of step  2  :

    4     1      9 
  (—— +  ——) +  ———
   25    25     100

Step  3  :

             4
 Simplify   ——
            25

Equation at the end of step  3  :

    4     1      9 
  (—— +  ——) +  ———
   25    25     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:

 4 + 1     1
 —————  =  —
  25       5

Equation at the end of step  4  :

  1     9 
  — +  ———
  5    100

Step  5  :

Calculating the Least Common Multiple :

 5.1    Find the Least Common Multiple

      The left denominator is :       5 

      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 = 20

   Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

 5.3      Rewrite the two fractions into equivalent fractions

   L. Mult. • L. Num.       20
   ——————————————————  =   ———
         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:

 20 + 9      29
 ——————  =  ———
  100       100

Final result :

   29           
  ——— = 0.29000 
  100
