Solution - Adding, subtracting and finding the least common multiple

Step  1  :

             5
 Simplify   ——
            26

Equation at the end of step  1  :

        11      5
  (0 -  ——) -  ——
        13     26

Step  2  :

            11
 Simplify   ——
            13

Equation at the end of step  2  :

        11      5
  (0 -  ——) -  ——
        13     26

Step  3  :

Calculating the Least Common Multiple :

 3.1    Find the Least Common Multiple

      The left denominator is :       13 

      The right denominator is :       26 

      Least Common Multiple:
      26 

Calculating Multipliers :

 3.2    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 :

 3.3      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.      -11 • 2
   ——————————————————  =   ———————
         L.C.M               26   

   R. Mult. • R. Num.       5
   ——————————————————  =   ——
         L.C.M             26

Adding fractions that have a common denominator :

 3.4       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:

 -11 • 2 - (5)     -27
 —————————————  =  ———
      26           26 

Final result :

  -27            
  ——— = -1.03846 
  26
