Solution - Reducing fractions to their lowest terms

Step  1  :

            72
 Simplify   ——
            7 

Equation at the end of step  1  :

              72
  50 +  (0 -  ——)
              7 

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  7  as the denominator :

           50     50 • 7
     50 =  ——  =  ——————
           1        7   

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 :

 2.2       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:

 50 • 7 + -72     278
 ————————————  =  ———
      7            7 

Final result :

  278            
  ——— = 39.71429 
   7
