Solution - Adding, subtracting and finding the least common multiple

Step  1  :

            31
 Simplify   ——
            5 

Equation at the end of step  1  :

   31    21     31
  (—— +  ——) +  ——
   4     4      5 

Step  2  :

            21
 Simplify   ——
            4 

Equation at the end of step  2  :

   31    21     31
  (—— +  ——) +  ——
   4     4      5 

Step  3  :

            31
 Simplify   ——
            4 

Equation at the end of step  3  :

   31    21     31
  (—— +  ——) +  ——
   4     4      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:

 31 + 21     13
 ———————  =  ——
    4        1 

Equation at the end of step  4  :

  13    31
  —— +  ——
  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 :

           13     13 • 5
     13 =  ——  =  ——————
           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:

 13 • 5 + 31     96
 ———————————  =  ——
      5          5 

Final result :

  96            
  —— = 19.20000
