  (——— -  ——) -  ——
   10     10     10

Step  3  :

            131
 Simplify   ———
            10 

Equation at the end of step  3  :

   131    13     37
  (——— -  ——) -  ——
   10     10     10

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:

 131 - (13)     59
 ——————————  =  ——
     10         5 

Equation at the end of step  4  :

  59    37
  —— -  ——
  5     10

Step  5  :

Calculating the Least Common Multiple :

 5.1    Find the Least Common Multiple

      The left denominator is :       5 

      The right denominator is :       10 

      Least Common Multiple:
      10 

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 = 2

   Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

 5.3      Rewrite the two fractions into equivalent fractions

   L. Mult. • L. Num.      59 • 2
   ——————————————————  =   ——————
         L.C.M               10  

   R. Mult. • R. Num.      37
   ——————————————————  =   ——
         L.C.M             10

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:

 59 • 2 - (37)     81
 —————————————  =  ——
      10           10

Final result :

  81           
  —— = 8.10000
