Step  1  :

            322
 Simplify   ———
             5 

Equation at the end of step  1  :

   871    322     
  (——— +  ———) +  84
   10      5      

Step  2  :

            871
 Simplify   ———
            10 

Equation at the end of step  2  :

   871    322     
  (——— +  ———) +  84
   10      5      

Step  3  :

Calculating the Least Common Multiple :

 3.1    Find the Least Common Multiple

      The left denominator is :       10 

      The right denominator is :       5 

      Least Common Multiple:
      10 

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 = 1

   Right_M = L.C.M / R_Deno = 2

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.      871
   ——————————————————  =   ———
         L.C.M             10 

   R. Mult. • R. Num.      322 • 2
   ——————————————————  =   ———————
         L.C.M               10   

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:

 871 + 322 • 2     303
 —————————————  =  ———
      10            2 

Equation at the end of step  3  :

  303    
  ——— +  84
   2     

Step  4  :

Rewriting the whole as an Equivalent Fraction :

 4.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  2  as the denominator :

          84     84 • 2
    84 =  ——  =  ——————
          1        2   

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

 4.2       Adding up the two equivalent fractions

 303 + 84 • 2     471
 ————————————  =  ———
      2            2 

Final result :

  471             
  ——— = 235.50000
