Step  1  :

            91
 Simplify   ——
            5 

Equation at the end of step  1  :

   168          91
  (——— +  7) +  ——
   10           5 

Step  2  :

            84
 Simplify   ——
            5 

Equation at the end of step  2  :

   84          91
  (—— +  7) +  ——
   5           5 

Step  3  :

Rewriting the whole as an Equivalent Fraction :

 3.1   Adding a whole to a fraction

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

         7     7 • 5
    7 =  —  =  —————
         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 :

 3.2       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:

 84 + 7 • 5     119
 ——————————  =  ———
     5           5 

Equation at the end of step  3  :

  119    91
  ——— +  ——
   5     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 + 91     42
 ————————  =  ——
    5         1 

Final result :

  42
