Solution - Reducing fractions to their lowest terms

Step  1  :

             9
 Simplify   ——
            25

Equation at the end of step  1  :

        9
  1 -  ——
       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 :

          1     1 • 25
     1 =  —  =  ——————
          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:

 25 - (9)     16
 ————————  =  ——
    25        25

Final result :

  16           
  —— = 0.64000 
  25
