Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "0.84" was replaced by "(84/100)".

Step  1  :

            21
 Simplify   ——
            25

Equation at the end of step  1  :

       21
  3 -  ——
       25

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  25  as the denominator :

          3     3 • 25
     3 =  —  =  ——————
          1       25  

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:

 3 • 25 - (21)     54
 —————————————  =  ——
      25           25

Final result :

  54           
  —— = 2.16000 
  25
