Step  1  :

            41
 Simplify   ——
            10

Equation at the end of step  1  :

   162    12     41
  (——— -  ——) -  ——
   10     10     10

Step  2  :

            6
 Simplify   —
            5

Equation at the end of step  2  :

   162    6     41
  (——— -  —) -  ——
   10     5     10

Step  3  :

            81
 Simplify   ——
            5 

Equation at the end of step  3  :

   81    6     41
  (—— -  —) -  ——
   5     5     10

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:

 81 - (6)     15
 ————————  =  ——
    5         1 

Equation at the end of step  4  :

  15    41
  —— -  ——
  1     10

Step  5  :

Rewriting the whole as an Equivalent Fraction :

 5.1   Subtracting a fraction from a whole

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

           15     15 • 10
     15 =  ——  =  ———————
           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 :

 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:

 15 • 10 - (41)     109
 ——————————————  =  ———
       10           10 

Final result :

  109            
  ——— = 10.90000
