Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): ".721" was replaced by "(721/1000)".

Step  1  :

             721
 Simplify   ————
            1000

Equation at the end of step  1  :

        721     
  (r • ————) -  16
       1000     

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  1000  as the denominator :

          16     16 • 1000
    16 =  ——  =  —————————
          1        1000   

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:

 721r - (16 • 1000)     721r - 16000
 ——————————————————  =  ————————————
        1000                1000    

Final result :

  721r - 16000
  ————————————
      1000
