Step  1  :

            21
 Simplify   ——
            5 

Equation at the end of step  1  :

   119    19     21
  (——— -  ——) -  ——
   10     10     5 

Step  2  :

            19
 Simplify   ——
            10

Equation at the end of step  2  :

   119    19     21
  (——— -  ——) -  ——
   10     10     5 

Step  3  :

            119
 Simplify   ———
            10 

Equation at the end of step  3  :

   119    19     21
  (——— -  ——) -  ——
   10     10     5 

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:

 119 - (19)     10
 ——————————  =  ——
     10         1 

Equation at the end of step  4  :

  10    21
  —— -  ——
  1     5 

Step  5  :

Rewriting the whole as an Equivalent Fraction :

 5.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  5  as the denominator :

           10     10 • 5
     10 =  ——  =  ——————
           1        5   

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:

 10 • 5 - (21)     29
 —————————————  =  ——
       5           5 

Final result :

  29           
  —— = 5.80000
