Solution - Reducing fractions to their lowest terms

Step  1  :

            169
 Simplify   ———
            125

Equation at the end of step  1  :

       169
  1 -  ———
       125

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  125  as the denominator :

          1     1 • 125
     1 =  —  =  ———————
          1       125  

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:

 125 - (169)     -44
 ———————————  =  ———
     125         125

Final result :

  -44            
  ——— = -0.35200 
  125
