Step  1  :

            799
 Simplify   ———
            100

Equation at the end of step  1  :

      146     382   799
  ((0-———)+(0-———))+———
      100     100   100

Step  2  :

            191
 Simplify   ———
            50 

Equation at the end of step  2  :

         146           191      799
  ((0 -  ———) +  (0 -  ———)) +  ———
         100           50       100

Step  3  :

            73
 Simplify   ——
            50

Equation at the end of step  3  :

         73     -191     799
  ((0 -  ——) +  ————) +  ———
         50      50      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:

 -73 + -191     -132
 ——————————  =  ————
     50          25 

Equation at the end of step  4  :

  -132    799
  ———— +  ———
   25     100

Step  5  :

Calculating the Least Common Multiple :

 5.1    Find the Least Common Multiple

      The left denominator is :       25 

      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 = 4

   Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

 5.3      Rewrite the two fractions into equivalent fractions

   L. Mult. • L. Num.      -132 • 4
   ——————————————————  =   ————————
         L.C.M               100   

   R. Mult. • R. Num.      799
   ——————————————————  =   ———
         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:

 -132 • 4 + 799     271
 ——————————————  =  ———
      100           100

Final result :

  271           
  ——— = 2.71000 
  100
