Step  1  :

            34
 Simplify   ——
            5 

Equation at the end of step  1  :

   63    87           34
  (—— +  ——) +  (0 -  ——)
   10    10           5 

Step  2  :

            87
 Simplify   ——
            10

Equation at the end of step  2  :

   63    87     -34
  (—— +  ——) +  ———
   10    10      5 

Step  3  :

            63
 Simplify   ——
            10

Equation at the end of step  3  :

   63    87     -34
  (—— +  ——) +  ———
   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:

 63 + 87     15
 ———————  =  ——
   10        1 

Equation at the end of step  4  :

  15    -34
  —— +  ———
  1      5 

Step  5  :

Rewriting the whole as an Equivalent Fraction :

 5.1   Adding a fraction to a whole

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

           15     15 • 5
     15 =  ——  =  ——————
           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:

 15 • 5 + -34     41
 ————————————  =  ——
      5           5 

Final result :

  41           
  —— = 8.20000
