Step  4  :

Calculating the Least Common Multiple :

 4.1    Find the Least Common Multiple

      The left denominator is :       40 

      The right denominator is :       10 

      Least Common Multiple:
      40 

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 = 1

   Right_M = L.C.M / R_Deno = 4

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.      259
   ——————————————————  =   ———
         L.C.M             40 

   R. Mult. • R. Num.      9 • 4
   ——————————————————  =   —————
         L.C.M              40  

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:

 259 + 9 • 4     59
 ———————————  =  ——
     40          8 

Equation at the end of step  4  :

  59    72
  —— +  ——
  8     25

Step  5  :

Calculating the Least Common Multiple :

 5.1    Find the Least Common Multiple

      The left denominator is :       8 

      The right denominator is :       25 

      Least Common Multiple:
      200 

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 = 25

   Right_M = L.C.M / R_Deno = 8

Making Equivalent Fractions :

 5.3      Rewrite the two fractions into equivalent fractions

   L. Mult. • L. Num.      59 • 25
   ——————————————————  =   ———————
         L.C.M               200  

   R. Mult. • R. Num.      72 • 8
   ——————————————————  =   ——————
         L.C.M              200  

Adding fractions that have a common denominator :

 5.4       Adding up the two equivalent fractions

 59 • 25 + 72 • 8     2051
 ————————————————  =  ————
       200            200 

Final result :

  2051            
  ———— = 10.25500
