Step  1  :

             73
 Simplify   ———
            100

Equation at the end of step  1  :

   49     73     
  (—— +  ———) +  7
   10    100     

Step  2  :

            49
 Simplify   ——
            10

Equation at the end of step  2  :

   49     73     
  (—— +  ———) +  7
   10    100     

Step  3  :

Calculating the Least Common Multiple :

 3.1    Find the Least Common Multiple

      The left denominator is :       10 

      The right denominator is :       100 

      Least Common Multiple:
      100 

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 = 10

   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.      49 • 10
   ——————————————————  =   ———————
         L.C.M               100  

   R. Mult. • R. Num.       73
   ——————————————————  =   ———
         L.C.M             100

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:

 49 • 10 + 73     563
 ————————————  =  ———
     100          100

Equation at the end of step  3  :

  563    
  ——— +  7
  100    

Step  4  :

Rewriting the whole as an Equivalent Fraction :

 4.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  100  as the denominator :

         7     7 • 100
    7 =  —  =  ———————
         1       100  

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

 563 + 7 • 100     1263
 —————————————  =  ————
      100          100 

Final result :

  1263            
  ———— = 12.63000 
  100
