Step  3  :

Calculating the Least Common Multiple :

 3.1    Find the Least Common Multiple

      The left denominator is :       11 

      The right denominator is :       3 

      Least Common Multiple:
      33 

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 = 3

   Right_M = L.C.M / R_Deno = 11

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.       3
   ——————————————————  =   ——
         L.C.M             33

   R. Mult. • R. Num.      11
   ——————————————————  =   ——
         L.C.M             33

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:

 3 - (11)     -8
 ————————  =  ——
    33        33

Equation at the end of step  3  :

  1    -8
  — +  ——
  3    33

Step  4  :

            1
 Simplify   —
            3

Equation at the end of step  4  :

  1    -8
  — +  ——
  3    33

Step  5  :

Calculating the Least Common Multiple :

 5.1    Find the Least Common Multiple

      The left denominator is :       3 

      The right denominator is :       33 

      Least Common Multiple:
      33 

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 = 11

   Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

 5.3      Rewrite the two fractions into equivalent fractions

   L. Mult. • L. Num.      11
   ——————————————————  =   ——
         L.C.M             33

   R. Mult. • R. Num.      -8
   ——————————————————  =   ——
         L.C.M             33

Adding fractions that have a common denominator :

 5.4       Adding up the two equivalent fractions

 11 + -8      1
 ———————  =  ——
   33        11

Final result :

   1           
  —— = 0.09091
