Solution - Reducing fractions to their lowest terms

Step  1  :

            3
 Simplify   —
            7

Equation at the end of step  1  :

           3
  21000 -  —
           7

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

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

              21000     21000 • 7
     21000 =  —————  =  —————————
                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:

 21000 • 7 - (3)     146997
 ———————————————  =  ——————
        7              7   

Final result :

  146997               
  —————— = 20999.57143
