Step  1  :

            5
 Simplify   —
            2

Equation at the end of step  1  :

    25 25  25  5
  ((——+——)+——)+—
    10 10  10  2

Step  2  :

            5
 Simplify   —
            2

Equation at the end of step  2  :

    25    25     5     5
  ((—— +  ——) +  —) +  —
    10    10     2     2

Step  3  :

            5
 Simplify   —
            2

Equation at the end of step  3  :

    25    5     5     5
  ((—— +  —) +  —) +  —
    10    2     2     2

Step  4  :

            5
 Simplify   —
            2

Equation at the end of step  4  :

    5    5     5     5
  ((— +  —) +  —) +  —
    2    2     2     2

Step  5  :

Adding fractions which have a common denominator :

 5.1       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:

 5 + 5     5
 —————  =  —
   2       1

Equation at the end of step  5  :

   5    5     5
  (— +  —) +  —
   1    2     2

Step  6  :

Rewriting the whole as an Equivalent Fraction :

 6.1   Adding a fraction to a whole

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

          5     5 • 2
     5 =  —  =  —————
          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 :

 6.2       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:

 5 • 2 + 5     15
 —————————  =  ——
     2         2 

Equation at the end of step  6  :

  15    5
  —— +  —
  2     2

Step  7  :

Adding fractions which have a common denominator :

 7.1       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:

 15 + 5     10
 ——————  =  ——
   2        1 

Final result :

  10
