Step  1  :

            5
 Simplify   —
            2

Equation at the end of step  1  :

   115     5     5
  (——— -  ——) -  —
   10     10     2

Step  2  :

            1
 Simplify   —
            2

Equation at the end of step  2  :

   115    1     5
  (——— -  —) -  —
   10     2     2

Step  3  :

            23
 Simplify   ——
            2 

Equation at the end of step  3  :

   23    1     5
  (—— -  —) -  —
   2     2     2

Step  4  :

Adding fractions which have a common denominator :

 4.1       Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

 23 - (1)     11
 ————————  =  ——
    2         1 

Equation at the end of step  4  :

  11    5
  —— -  —
  1     2

Step  5  :

Rewriting the whole as an Equivalent Fraction :

 5.1   Subtracting a fraction from a whole

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

           11     11 • 2
     11 =  ——  =  ——————
           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 :

 5.2       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:

 11 • 2 - (5)     17
 ————————————  =  ——
      2           2 

Final result :

  17           
  —— = 8.50000
