Step  1  :

            9
 Simplify   —
            4

Equation at the end of step  1  :

   125    175     9
  (——— +  ———) +  —
   100    100     4

Step  2  :

            7
 Simplify   —
            4

Equation at the end of step  2  :

   125    7     9
  (——— +  —) +  —
   100    4     4

Step  3  :

            5
 Simplify   —
            4

Equation at the end of step  3  :

   5    7     9
  (— +  —) +  —
   4    4     4

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:

 5 + 7     3
 —————  =  —
   4       1

Equation at the end of step  4  :

  3    9
  — +  —
  1    4

Step  5  :

Rewriting the whole as an Equivalent Fraction :

 5.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  4  as the denominator :

          3     3 • 4
     3 =  —  =  —————
          1       4  

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:

 3 • 4 + 9     21
 —————————  =  ——
     4         4 

Final result :

  21           
  —— = 5.25000
