Reformatting the input :

Changes made to your input should not affect the solution:

(1): "9.3" was replaced by "(93/10)". 2 more similar replacement(s)

Step  1  :

            93
 Simplify   ——
            10

Equation at the end of step  1  :

      35         93
  (7•(——+2))+(8•(——-7))
      10         10

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  10  as the denominator :

         7     7 • 10
    7 =  —  =  ——————
         1       10  

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 :

 2.2       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:

 93 - (7 • 10)     23
 —————————————  =  ——
      10           10

Equation at the end of step  2  :

        35                23
  (7 • (—— +  2)) +  (8 • ——)
        10                10

Step  3  :

            7
 Simplify   —
            2

Equation at the end of step  3  :

        7           92
  (7 • (— +  2)) +  ——
        2           5 

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 :

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

Adding fractions that have a common denominator :

 4.2       Adding up the two equivalent fractions

 7 + 2 • 2     11
 —————————  =  ——
     2         2 

Equation at the end of step  4  :

       11     92
  (7 • ——) +  ——
       2      5 

Step  5  :

Calculating the Least Common Multiple :

 5.1    Find the Least Common Multiple

      The left denominator is :       2 

      The right denominator is :       5 

      Least Common Multiple:
      10 

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 = 5

   Right_M = L.C.M / R_Deno = 2

Making Equivalent Fractions :

 5.3      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.      77 • 5
   ——————————————————  =   ——————
         L.C.M               10  

   R. Mult. • R. Num.      92 • 2
   ——————————————————  =   ——————
         L.C.M               10  

Adding fractions that have a common denominator :

 5.4       Adding up the two equivalent fractions

 77 • 5 + 92 • 2     569
 ———————————————  =  ———
       10            10 

Final result :

  569            
  ——— = 56.90000
