Reformatting the input :

Changes made to your input should not affect the solution:

(1): "0.8" was replaced by "(8/10)". 2 more similar replacement(s)

Step  1  :

            4
 Simplify   —
            5

Equation at the end of step  1  :

   124    4     
  (——— -  —) -  3
   10     5     

Step  2  :

            62
 Simplify   ——
            5 

Equation at the end of step  2  :

   62    4     
  (—— -  —) -  3
   5     5     

Step  3  :

Adding fractions which have a common denominator :

 3.1       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:

 62 - (4)     58
 ————————  =  ——
    5         5 

Equation at the end of step  3  :

  58    
  —— -  3
  5     

Step  4  :

Rewriting the whole as an Equivalent Fraction :

 4.1   Subtracting a whole from a fraction

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

         3     3 • 5
    3 =  —  =  —————
         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 :

 4.2       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:

 58 - (3 • 5)     43
 ————————————  =  ——
      5           5 

Final result :

  43           
  —— = 8.60000
