Step  1  :

            71
 Simplify   ——
            10

Equation at the end of step  1  :

    54 36  91  71
  ((——+——)+——)+——
    10 10  10  10

Step  2  :

            91
 Simplify   ——
            10

Equation at the end of step  2  :

    54    36     91     71
  ((—— +  ——) +  ——) +  ——
    10    10     10     10

Step  3  :

            18
 Simplify   ——
            5 

Equation at the end of step  3  :

    54    18     91     71
  ((—— +  ——) +  ——) +  ——
    10    5      10     10

Step  4  :

            27
 Simplify   ——
            5 

Equation at the end of step  4  :

    27    18     91     71
  ((—— +  ——) +  ——) +  ——
    5     5      10     10

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:

 27 + 18     9
 ———————  =  —
    5        1

Equation at the end of step  5  :

   9    91     71
  (— +  ——) +  ——
   1    10     10

Step  6  :

Rewriting the whole as an Equivalent Fraction :

 6.1   Adding a fraction to a whole

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

          9     9 • 10
     9 =  —  =  ——————
          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 :

 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:

 9 • 10 + 91     181
 ———————————  =  ———
     10          10 

Equation at the end of step  6  :

  181    71
  ——— +  ——
  10     10

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:

 181 + 71     126
 ————————  =  ———
    10         5 

Final result :

  126            
  ——— = 25.20000
