Step  1  :

            7
 Simplify   —
            2

Equation at the end of step  1  :

   175     5     7
  (——— -  ——) -  —
   10     10     2

Step  2  :

            1
 Simplify   —
            2

Equation at the end of step  2  :

   175    1     7
  (——— -  —) -  —
   10     2     2

Step  3  :

            35
 Simplify   ——
            2 

Equation at the end of step  3  :

   35    1     7
  (—— -  —) -  —
   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:

 35 - (1)     17
 ————————  =  ——
    2         1 

Equation at the end of step  4  :

  17    7
  —— -  —
  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 :

           17     17 • 2
     17 =  ——  =  ——————
           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:

 17 • 2 - (7)     27
 ————————————  =  ——
      2           2 

Final result :

  27            
  —— = 13.50000
