Step  4  :

 4.1      Finding a Common Denominator   The left  40000 
 The right  29 • 56 

 The product of any two denominators can be used
 as a common denominator. 

 Said product is not necessarily the least common 
 denominator.

 As a matter of fact, whenever the two denominators
have a common factor, their product will be bigger
 than the least common denominator. 

Anyway, the product is a fine common denominator and
 can perfectly be used for 
 calculating multipliers, as well as for generating
 equivalent fractions. 

 40000 • 29 • 56   will be used as a common denominator.

Calculating Multipliers :

 4.2    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 = 2⁹ • 5⁶

   Right_M = L.C.M / R_Deno = 40000

Making Equivalent Fractions :

 4.3      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 • (29•56)  
   ——————————————————  =               ———————————————
             Common denominator        40000 • (29•56)

   R. Mult. • R. Num.                     27 • 40000  
   ——————————————————  =               ———————————————
             Common denominator        40000 • (29•56)

Adding fractions that have a common denominator :

 4.4       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 • (29•56) - (27 • 40000)     3•29•56 - 1080000
 ——————————————————————————  =  —————————————————
      40000 • (29•56)            40000 • (29•56) 

Step  5  :

Pulling out like terms :

 5.1     Pull out like factors :

   3 • 2⁹ • 5⁶ - 1080000  =   3 • (1 - 360000) 

Final result :

  3 • (1 + 360000)
